<br />
Before the aluminum be proceed by anodizing, the material must treat use electropolishing first, this process will open the surface film above the aluminum part, because in the store or travel after the aluminum be produced will react with free air build an aluminum oxide that cover the surface of aluminum. To open the surface pore can't use just dipped in water but must use electric current. Even if dipped in hot water the pores can be closed.<br />

<a href="https://www.blogger.com/u/1/null" id="Art1">Electropolishing Definition</a></h3>
<br />
Electropolishing is an excellent preparation of metals for electroplating, this is a kind of metal surface treatment before <a href="https://anodizing-process.blogspot.co.id/">anodizing process</a> or other kind of process. In addition to providing a chemically and physically clean surface, electropolishing removes mechanically surface damage. As a result, subsequent electroplates have the best adhesion possible and a decreased tendency toward developing pits and voids that lower corrosion protection. Metal surfaces that have been machined, ground, picked and rolled, abrasive polished, and buffed, have asperities that are detrimental to uniform and pit-free electroplates, adhesion of the plate, and strength of the interface region of the plate basis metal. <br />
<br />

Electropolishing is a process of producing a polished and bright limit on the surface of metals. In this process the metal part or the device to be coated with a layer of suitable metal is immersed, as the anode in a solution having such a composition that when the metal is made the anode, there occur unstable conditions of passivity which manifest themselves by an anomalous change in current strength is adjusted to give a current density, previously determined by observation, which is characteristic for the given metal and the given solution, at which there occurs the transformation of the Matt surface into a bright polished one.<br />
<br />
<h3>
<a href="https://www.blogger.com/u/1/null" id="Art2">Electropolishing Bath:</a></h3>
<br />
The most common used in electropolishing bath are based on sulfuric and phosphoric acids in about 50/50 weight proportion at about 54 to 105 <sup>o</sup>C for ferrous alloys, 85% phosphoric acid for copper at about 43 to 60 <sup>o</sup>C; and phosphoric acid with about 5 to 7% chromic anhydride (CrO<sub>3</sub>) at about 60 <sup>o</sup>C for brass.<br />
<br />
Current density of practical electropolishing range from 5 to 40 A/dm2, depending on the metal being finished, type of bath, and temperature. The time required usually is 2 to 7 min for current densities of 15 to 30 A/dm<sup>2</sup> and temperature of 54 to 82 <sup>o</sup>C.<br />
<br />
The solution used for the <a href="http://anodizing-process.blogspot.com/2008/02/polishing-after-anodized.html">polishing of aluminum</a> can be divided into two groups. The first of these includes the phosphate, alkaline and fluoboric acid solution. They are characterized by a low rate of dissolution of the metal and are used as a finishing treatment for mechanically polished parts with a view to obtain a very high reflectivity. They are employed for treatment of reflectors where a high coefficient of reflection can’t be obtained by mechanical polishing alone. The fluoboric acid and the phosphate electrolytes are suitable only for treatment of aluminum of high purity. The second group includes solutions containing phosphoric acid, sulfuric and <a href="https://chemistry-grahito.blogspot.co.id/2009/06/chromic-acid.html">chromic acid</a>. They are characterized by a higher rate of dissolution of the metal than the solutions belonging to the first group, and they enable the smoothing out of microasparities and the production of a bright, but not a mirror finished surface. These solution are used in place of mechanical surface finishing operations for parts of aluminum of different purity grades and for certain wrought aluminum alloys. In addition to the above, solutions of perchloric acid and acetic anhydride have also been recommended for the polishing of aluminum. The use of these electrolytes, however, involves taking certain precautions because of the risk of explosions.<br />
<br />
The purity of aluminum is an important factor in electropolishing of the metal. An appreciable increase in reflectivity can achieved only in able amount of admixtures is much less satisfactory. Very often polishing becomes impossible because of the non-uniform dissolution of the surface of the anode. This factor renders difficult the polishing of aluminum alloys, especially those containing silicon. For the treatment of castings of an aluminum alloy containing 5 per cent silicon, an electrolyte comprising 13 per cent hydro-fluoroboric acid and 52 percent glycerin is recommended. The solution is used at 25 0C with a current density of 200 amp./sq.ft., the time of polishing being 10 minutes. During polishing the solution is stirred.<br />

<h2>
<b><a href="https://www.blogger.com/u/1/null" id="Art1">Aluminum Anodizing Practice</a></b></h2>
<b>Aluminum anodizing</b> is a process to cover aluminum surface with substance below the oxidized aluminum layer on the surface. This layer is very thin and transparent so the substance below this surface can be seen and can be coloring etc. To make aluminum surface have good color usually use textile coloring agent. <br />
<br />
The electro deposition of anodized aluminum has been investigated for use in coating steel strip, in electrorefening and in the cladding of uranium. Upto 76-cm diameter parabolic mirrors have been electroformed in 750-liter solutions. Limited commercial applications of aluminum plating have been reported.<br />
<br />
Aluminum, because it is much more chemically active than hydrogen, probably cannot be electrodeposited from solution that contain water or any other compound with an acidic hydrogen, for example, acids, alcohols, esters, ammonia, and primary and secondary amines. It can be electrodeposited from inorganic and organic fused salt mixtures and from solutions of <a href="http://anodizing-process.blogspot.co.id/2008/02/aluminum-definition.html" title="aluminum definition">aluminum</a> compounds in certain organic solvents, only the National Bureau of Standards hydride process has achieved a modest degree of use and is considered in this chapter.<br />

<h2>
<a href="https://www.blogger.com/u/1/null" id="Art2">Aluminum Anodizing Steps:</a></h2>
The step to anodized aluminum should be as follows:<br />
<br />
<h3>
1. <a href="https://www.blogger.com/u/1/null" id="Art3">Electropolishing of Aluminum</a></h3>
Before the aluminum being proceed by anodizing, the material must treat use <a href="http://anodizing-process.blogspot.co.id/2008/01/electropolishing-of-aluminum.html" title="electropolishing of aluminum">electropolishing </a>first, this process will open the surface film above the aluminum surface, because in the store or travel after the aluminum be produced will react with free air build an aluminum oxide that cover the surface of aluminum. On this process aluminum oxide film like being peeled up. To open the surface pore can't use just dipped in water but must use electric current. Even if dipped in hot water the pores still closed. To open before aluminum anodized should proceed in electric current on the acid solution.<br />
<br />
<h3>
2. <a href="https://www.blogger.com/u/1/null" id="Art4">Alkaline Solution Treatment</a></h3>
The next step of aluminum anodizing is treated in <a href="http://anodizing-process.blogspot.co.id/2008/01/alkaline-solution.html" title="alkaline solution">alkali solution.</a> The concentration of free alkali in the solution is one of the major factors which determines the program of the polishing process when treating aluminum in an alkaline solution. Although alkali is not one of the constituents used in making up the solution. It is formed in the bath as a result of hydrolysis. As the solution is used, the concentration of free alkali rises as a result of reaction of aluminum with sodium hydrogen phosphate. The optimum of alkali in the solution is 15 – 18 gram per liter.<br />
<br />
<h3>
3. <a href="https://www.blogger.com/u/1/null" id="Art5">Rinsing</a></h3>
Rinsing is a process that does in between of aluminum anodizing process step, <a href="http://anodizing-process.blogspot.co.id/2008/11/rinsing.html" title="rinsing">rinsing</a> also do in preparation for plating. The result quality will depend on the rinsing process, if many chemicals or organic substance left on the metal surface will result a bad electroplated or anodized product.<br />
<br />
<h3>
4. <a href="https://www.blogger.com/u/1/null" id="Art6">Jigging</a></h3>
<a href="http://anodizing-process.blogspot.co.id/2008/02/jigging.html">Jigging</a> is a process to parts which have been polished with polishing pastes are degreased using organic solvent, such as benzine or dichloromethane, and are dried in air until the traces of the solvent is disappeared. They are then mounted on anodizing jigs made of aluminum or clad alloy. The design of the jig requires special considerations. It should ensure a firm contact with both the work and the anode bar and at the same time the area of contact should be as small as possible because this area will remain not anodized. It should be just sufficient to avoid local heating of the metal, which is usually the cause of an attack on the surface of the work during the anodizing process. <br />
<br />
<h3>
5. <a href="https://www.blogger.com/u/1/null" id="Art7">Aluminum Anodizing</a></h3>
<a href="http://anodizing-process.blogspot.co.id/2008/02/anodizing.html">Aluminum anodizing</a> takes into account the composition of the solution, the alloy and the service requirement. To maintain the required temperature cooling arrangements in the case of sulfuric acid anodizing and heating solution is agitated by means of compressed air which is introduced trough a perforated coiled pipe arranged along the bottom of the vat. The cathodes used in anodizing baths, especially those of sulfuric acid, is very great. It is therefore almost unnecessary to use auxiliary cathodes when anodizing of the interior of pipes. If the length of the pipe exceed ten time the diameter, an internal cathode must be used.<br />
<br />
<h3>
6.<a href="https://www.blogger.com/u/1/null" id="Art8">Racking and Rinsing</a></h3>
Aluminum racks are preferred for plating aluminum alloys. It is recommended that 1100 alloy be used for the spines and 2024 alloys for the contacts. By increasing the cross sectional area of the spines by about 40%, a conductance equal of that of a copper rack is obtained. Where contact marks are not important, regular phosphor-bronze contact may be used. When phosphor-bronze contacts are used, however, the area adjacent to the contact may develop a small blister as a result of galvanic action in the zinc immersion bath. When nitric-hydrofluoric acids etch is used for conditioning, aluminum contacts should be used. <a href="http://anodizing-process.blogspot.co.id/2008/05/racking-and-rinsing.html">Racking and rinsing</a> several time to make sure that the part really clean.<br />
<br />
<h3>
7. <a href="https://www.blogger.com/u/1/null" id="Art9">Sealing and Coloring</a></h3>
The oxide films obtained after aluminum is anodized have considerable porosity and high adsorption capacity. <a href="http://anodizing-process.blogspot.co.id/2008/02/sealing-oxide-film.html" title="sealing oxide film">Sealing</a> of the film increases their resistances to corrosion and improves their electrical insulating properties. Sealing is essential for films that have been produced by anodizing in sulfuric acid, because only after sealing do the film acquire a sufficiently high resistance to corrosion, because surface of aluminum is anodized. The following methods can be used for sealing anodic oxide films:<br />
<br />
<h3>
8. <a href="https://www.blogger.com/u/1/null" id="Art10">Polishing after Anodized</a></h3>
One of the major applications of anodized aluminum involves the production of finishes resembling bronze, brass, gold, silver and their alloys. In such cases apart from the choice of suitable coloring materials, an important part is played by the conditioning and preparation of the surface of the metal prior to anodizing. <a href="http://anodizing-process.blogspot.co.id/2008/02/polishing-after-anodized.html">A mechanically polished surface</a> become dull after the first four minutes of anodizing in sulfuric acid. The absence of a metallic luster effects the appearance, the dyed film giving the appearance of a plastic surface. To retain the metallic lustrous, it is necessary to produce a passive film capable of withstanding the action of sulfuric acid. This can be achieved by electro polishing. After electro polishing, the surface of the metal retains its luster even after one hour's anodizing. A pretreatment of this nature also helps the production of more intense color.<br />

Beside less people use this service, also less people use pure aluminum metal to make something. Usually they just use the available product from the store that normally already anodized. So that is why this blog about anodizing also less visitor, or only few people want to know about anodizing.<br />
<br />
To know more about anodizing you can browse through this blog, many articles may useful for your preference.

Composition of aluminum alloy make the process condition of anodizing is conditioning in order can get good performance of anodized alloy. Surface finish, prior processing, temper or heat treatment are influence to the quality of anodic coatings. The limitations imposed by each of these variables on various condition of aluminum alloy are as follows:<br />
<br />
Chromic acid process should not use for anodize aluminum casting alloys containing more than 5% of Cu or more than 7.5% of total alloying elements, because this alloy can resulting of excessive pitting, and may burning. Sulfuric acid bath can be used for commercial alloys, while <a href="http://anodizing-process.blogspot.co.id/2017/11/hard-anodizing-aluminum.html" target="_blank">hard anodizing process</a> is usually apply in limited alloys containing less than 5% Cu and 7% Si. Choice of alloys is important when the product should have maximum corrosion or abrassive resistance required. Alloys contain of copper and copper magnesium is able to produce hard, corrosion resistance coating.<br />
<br />
Two kind of alloy can be anodized together in the same anodizing bath if the voltage requirement are identical, even simultaneous anodizing of two different alloy is not normal applied. This process can be more difficult for <a href="http://chemistry-grahito.blogspot.co.id/2009/06/sulfuric-acid.html" target="_blank">sulfuric acid</a> process than <a href="http://chemistry-grahito.blogspot.co.id/2009/06/chromic-acid.html" target="_blank">chromic acid</a> process. <br />

</script><br />
Finished anodizing will form an anodic film, and often time formed surface irregularities that are emphasized more by chromic acid bath than by sulfuric acid bath. For this reason, suggest that sulfuric acid bath is use instead of chromic acid bath where optimum corrosion or abrasion resistant surfaces are required. Clad sheet should be handled with careful to prevent mechanical abrasion or exposure of the core material. Scratch on surface of aluminum make this magnifies exposed, with different color of anodized finished. <br />
<br />
Anodizing grade must be specified for extruded products so that mill operations are controlled to minimize longitudinal die marks and other surface blemishes. Surface irregularities must be removed from <a href="http://carbon-steel.blogspot.co.id/2017/10/forge-steel-process.html" target="_blank">forgings</a>, and surface of forgings must be cleaned by a process that removes trapped and burned-in die lubricants.<br />
<br />
Castings can be anodized provided their composition is within the process limits described under alloy composition. Uniform will appearance, however anodizing usually is undesirable for castings. <br />

Special anodizing process is the condition of several <a href="http://anodizing-process.blogspot.co.id/" target="_blank">anodizing process</a> that is done from several process of by certain company or from proprietary information available to licencess only. Anodizing condition process that is proposed based on licence are Martin Hard Coat (MHC), Aluminate 225 and 226, Alcanodox Hardas, Sandford, Kalcolor and Lasser. <br />
<br />
<a href="http://anodizing-process.blogspot.co.id/2017/11/hard-anodizing-aluminum.html" target="_blank">Hard anodizing process</a> uses a sulfuric acid bath containing 10 to 20% of acid, with or without additives. Operating condition temperature of the bath range from 0 to 10 <sup><span style="font-size: 13.3333px;">o</span></sup>C, and with current density range between 2 and 3.6 A/dm<sup>2<span style="font-size: 13.3333px;"></span></sup>. By adding some additives and modifier for power, hard anodizing can be operated at higher temperature than room temperature. But hard anodizing that operate in higher temperature than room temperature may result soft formation and more porous outer layer. The change of character result will reduce wear resistance coating significantly and tends to limit coating thickness. If without use of some additives or modified power, such as superimposed alternating current over direct current or pulsed current, excessive operating temperatures result in dissolution of coating and can burnt and damage the work.<br />
<br />
Prefer <a href="http://anodizing-process.blogspot.co.id/2017/11/anodizing-condition-process.html" target="_blank">process condition</a> that are commonly use solution containing 120 to 160 g of <a href="http://chemistry-grahito.blogspot.co.id/2009/06/sulfuric-acid.html" target="_blank">sulfuric acid</a> and 12 to 20 g of <a href="http://chemistry-grahito.blogspot.co.id/2017/11/oxalic-acid.html">oxalic acid</a> per 3.8 lt water. Operating temperature at 10 + 1 <sup><span style="font-size: 13.3333px;">o</span></sup>C and use current density of 2.5 to 3.6 A/dm<sup>2<span style="font-size: 13.3333px;"></span></sup>, voltage is increase gradually from zero to 40 or 60 V. Time treatment about 25 minute will result anodizing thickness about 1 mil or 25 micron.<br />
<br />
For special condition process that mensioned above will use some parameter limitation as on the table below:<br />

Any part that formed from aluminum metal should be anodized because the properties of origin aluminum metal will improved and change into better properties. Even of many anodized product can make more stand to corrode or stand to scratch but <a href="http://anodizing-process.blogspot.co.id/2008/01/aluminum-anodizing.html" target="_blank">anodizing to aluminum</a> is purposed to certain purpose of anodizing. The below lists are some reason why people doing anodizing to aluminum, outlined on the below:<br />
<ol><li>Anodizing aluminum is purposed to increase corrosion resistance. Oxide film that formed on the surface of aluminum sheet can stand to corrode in atmospheric condition and salt water attack. So this oxide film can protect underlying metal by serving as barrier from attracting some corrosive agent. To make the oxide film can protect the aluminum sheet is treated the aluminum sheet after anodized into hot water with slightly acidified, or use dichromate solution, or nickel acetate solution.</li>
<li>Other reason to anodize aluminum improve decorative appearance. All anodic coating have lustrous and relatively good abrasion resistance. The degree of lustrous of anodic coating depends on the condition of aluminum before anodizing. Dull etching will decrease luster, bright etching, chemical or electrolytic brightening and buffing will increase luster either diffuse or spectacular. For this kind of aluminum finished are use in structural and architectural application. </li>
<li>Aluminum anodizing can increase abrasive resistance. From the experience product result the thickness of <a href="http://anodizing-process.blogspot.co.id/2017/11/hard-anodizing-aluminum.html" target="_blank">hard anodizing</a> about 25 micron (1mm) to more than 100 micron (4 mm). This thickness is enough for many applications that involving rotating parts where abrasion resistance is required. <br />

</script>
<li>Some anodizing process is purposed to increase paint adhesion. Alloy metal from aluminum can anodized to activate the surface of alloy metal. Aluminum base alloy materials that are painted for service in severe corrosive environment are anodized before painting. </li>
<li>Other reason of anodizing of aluminum alloy is improve adhesive bonding. This kind material are used in aircraft structure of most modern aircraft. Anodizing use phosphoric acid or chromic acid can improve bond strength and durability.</li>
<li>Anodizing process also can improve lubricity, by combination of polishing or honing of hard anodizing to smoother surface before applying a polytetrafluoroethylene coating.</li>
<li>General purpose of anodizing product is purpose for aesthetic performance, can provide unique, <a href="http://anodizing-process.blogspot.co.id/2009/11/anodizing-as-decorative-finished.html" target="_blank">decorative finished color</a>. As already discussed of mechanism of coloring in anodizing process, that sealing of anodizing aluminum is together with coloring of oxide film on the surface of aluminum. Integral anodizing, depending on the alloy composition, is used to provide a range of stable earth-tone colors suitable for architectural applications. </li>
<li>Anodizing process also purpose to provide electrical insulation. Aluminum oxide is a dielectric, that mean can’t conduct electric current until certain voltage. The breakdown voltage of anodic film varies from a few volts to several thousand volts. This depend on the alloy properties itself and on the natural and thickness of oxide film on the surface.</li>
<li>Anodizing of metal also make subsequent plating. The porosity of certain anodic films enhances <a href="http://electroplating-process.blogspot.co.id/" target="_blank">electroplating</a>. </li>
<li>Anodized surface of aluminum can detect of surface flaws. Chromic acid solution bath can be used as an inspection medium for detection of fine surface cracks. When object containing surface flaws is removed from anodizing bath, then washed and dried quickly, chromic acid entrapped in the flaws seeps out and stains in the anodized coating in around of the flaws. </li>

<b>Hard anodizing aluminum</b> is similar to <a href="http://anodizing-process.blogspot.co.id/2008/01/aluminum-anodizing.html" target="_blank">standard aluminum anodizing </a>in that are controlled by electrochemical processes. The key difference is that hard coat anodizing provides a surface more wear resistant and has a smoother and harder surface than standard anodizing. Hard anodizing aluminum will result a uniform aluminum oxide layer on the surface that penetrate the material pores. <a href="http://anodizing-process.blogspot.co.id/" target="_blank">Anodizing process</a> condition for hard anodizing involved by submersing part in sulfuric acid solution at room temperature from 20 minutes two hours. The longer time submerged determines the thickness of coating. Aluminum oxide formed in the surface during hardcoat anodizing is more uniform, dense, and much harder than the natural oxidation.<br />
<br />
<h3>The benefit of Hard Anodizing:</h3><br />
The benefit of hard coat anodizing have many, some reason to create hard coat for aluminum anodizing is as follows:<br />

Anodizing aluminum can be accomplished in wide variety of electrolytes, employing varying operation condition including concentration and composition of electrolyte. Anodizing can be process in several kind of process, that is used different anodizing bath solution, such as <a href="http://anodizing-process.blogspot.co.id/2011/03/chromic-acid-anodizing.html" target="_blank">chromic acid process</a>, <a href="http://anodizing-process.blogspot.co.id/2008/10/electropolishing-bath.html" target="_blank">sulfuric acid process</a>, and <a href="http://anodizing-process.blogspot.co.id/2008/02/anodizing-in-oxalic-acid.html" target="_blank">oxalic acid anodizing bath</a>. As on the table condition process of anodizing, there are two kind of anodizing process condition. For conventional anodizing and commercial anodizing process.<br />

The purity of aluminum is an important factor in <a href="http://anodizing-process.blogspot.co.id/2008/01/electropolishing-of-aluminum.html" target="_blank">electropolishing of the aluminum</a> metal. An appreciable increase in reflectivity can achieved only in amount of admixtures is much less satisfactory. Very often polishing becomes impossible because of the non-uniform dissolution of the surface of the anode.<br />
<br />
This factor renders difficult the polishing of aluminum alloys, especially those containing silicon. For the treatment of castings of an aluminum alloy containing 5 per cent silicon, an electrolyte comprising 13 per cent hydro-fluoroboric acid and 52 percent glycerin is recommended. The solution is used at 25 oC with a current density of 200 amp./sq.ft., the time of polishing being 10 minutes. During polishing the solution is stirred. <a href="http://anodizing-process.blogspot.co.id/2017/11/bath-condition-of-electropolishing.html" target="_blank">Bath chemicals and conditioning</a> are very dependent on the purpose of anodizing process.Adi Grahitohttp://www.blogger.com/profile/02037548534505573222noreply@blogger.comKota New York, New York, Amerika Serikat40.7127753 -74.005972839.9423093 -75.296866299999991 41.483241299999996 -72.7150793tag:blogger.com,1999:blog-7219030016364589775.post-71950847162622995932017-11-10T12:28:00.000+00:002017-11-13T00:31:33.932+00:00Bath Condition of Electropolishinghttp://anodizing-process.blogspot.co.id/2008/01/aluminum-anodizing.html<br />
<a href="http://anodizing-process.blogspot.co.id/2017/11/electropolishing-bath.html" target="_blank">Electropolishing bath</a> commonly are based on sulfuric and phosphoric acids in about 50 % by weight proportion and operate at about 54 to 105 oC for ferrous alloys, 85% phosphoric acid for copper at about 43 to 60 oC; and phosphoric acid with about 5 to 7% chromic anhydride (CrO3) at about 60 oC for brass.<br />
<br />
DC electric on this process is needed and the current density of <a href="http://anodizing-process.blogspot.co.id/2008/01/electropolishing-of-aluminum.html" target="_blank"> aluminum electropolishing</a> range from 5 to 40 A/dm2, depending on the metal being finished, type of bath, and temperature. The time required usually is 2 to 7 min for current densities of 15 to 30 A/dm2 and temperature of 54 to 82 oC. For higher current density the process can be faster but be careful because if to higher current density can make aluminum surface broken, better use electric current density increase gradually, this arrange to make better result of <a href="http://anodizing-process.blogspot.co.id/2008/01/aluminum-anodizing.html" target="_blank">aluminum anodizing</a>.Adi Grahitohttp://www.blogger.com/profile/02037548534505573222noreply@blogger.comKota New York, New York, Amerika Serikat40.7127753 -74.005972839.9423093 -75.296866299999991 41.483241299999996 -72.7150793tag:blogger.com,1999:blog-7219030016364589775.post-41646202957616267402017-11-10T12:24:00.001+00:002017-11-13T00:31:56.052+00:00Electropolishing BathTo make <a href="http://anodizing-process.blogspot.co.id/2008/01/electropolishing-of-aluminum.html">electropolishing of aluminum</a> need of some chemicals on bath. <a href="http://anodizing-process.blogspot.co.id/2017/11/chemical-for-polishing-of-aluminum.html" target="_blank">Chemical solution on electropolishing</a> bath can be different of every process, its depend on the purpose of <a href="http://anodizing-process.blogspot.co.id/" target="_blank">anodizing process</a>.

Especially for component that have riveted or welded assemblies where this is impossible to remove first before anodizing. <br />
<br />
Using this process will result of yellow to dark olive color finished, depending on the anode film thickness. For alloy metal like high contain <a href="http://carbon-steel.blogspot.co.id/2017/10/alloy.html#Art7" target="_blank">copper alloy</a>, the sequence of anodizing different with <a href="http://anodizing-process.blogspot.co.id/2008/01/aluminum-anodizing.html" target="_blank">aluminum anodizing</a>. <a href="http://chemistry-grahito.blogspot.co.id/2009/06/chromic-acid.html" target="_blank">Chromic acid</a> anodizing solution contain from 3 to 10% of CrO3 weight. To prepare this solution always attention to dissolve acid into water little by little don’t dilute water into acid, its can be dangerous. Because hot water contain acid can be splashed into your eyes.<br />
<br />
<h3>Chromic acid solution for alloy anodizing condition should be:</h3><ul><li>Have pH is between 0.5 and 1.0.</li>
<li>The concentration of chlorides (as sodium chloride) is less than 0.02%.</li>
<li>The concentration of sulfates (as <a href="http://chemistry-grahito.blogspot.co.id/2009/06/sulfuric-acid.html" target="_blank">sulfuric acid</a>) is less than 0.05%.</li>
<li>The total chromic acid content, as determined by pH and Baume readings, is less than 10%.</li>

When anodizing is started, the voltage is controlled so that it will increase from 0 to 40 V, don’t directly 40 Volt. This changes is increasing regularly in about 5 to 8 minutes. The voltage is regulated to produce a current density of not less than 0.1 A/dm 2 (1.0 A/ft2), and anodizing is continued for the required time, generally 30 to 40 min. For certain <a href="http://carbon-steel.blogspot.co.id/2017/10/alloy.html" target="_blank">alloy</a> can be fall if run in 40 volt, it should be run in 22 volt.

<h3>Step to apply clean and polishing aluminum</h3><ol><li>Wash aluminum steel with water and use regular dish soap. Use soft cloth or spon to scrub away any dirt that may already long time stay on the surface.</li>
<li>Rinse with water</li>
<li>Made a paste by mixed of tartar cream with little water to form paste.</li>
<li>Use soft cloth or sponge and apply paste to the surface of aluminum. With small circular moving start clean the surface.</li>
<li>Use small brush to clean detail of part like the corner in a piece.</li>
<li>Rinse again with water and let it dry by wiped with dry cloth.</li>
<li>Use aluminum polish and wipe into the surface of object with soft cloth. Polish substance only apply to aluminum pieces that are not used for food as it is not safe to be consumed. This polish can be apply to outside of pans or pots, but not to apply to object that will contact to burner or fire. With small circular moving rubbed the object with soft and clean cloth until shiny.</li>

This anodized aluminum is using brass as based metal. The product of anodized brass is very interested while this metal is one of alloy aluminum metal. This product need to be anodized on the surface because aluminum alloy also still react with outside air to make oxidized aluminum, the surface which is corroded to form oxide film aluminum oxide is very bad looking. After anodizing the surface of anodized brass and followed by sealing process this product became stand to corrode.<br />
<br />
Aluminum alloy product commonly used in aircraft structure, this <a href="https://anodizing-process.blogspot.co.id/2008/01/aluminum-anodizing.html">surface already anodized</a> in order stand to corrode. Even the color of surface still in natural color but the surface actually already anodized. Some of aircraft structure is not in natural color but white anodized color on their surface. <br />
Brass actually a kind of alloy that produce as follows: quote from <a href="http://carbon-steel.blogspot.co.id/2017/10/alloy.html#Art7">brass as alloy steel</a>.<br />
<blockquote class="tr_bq"><a href="http://carbon-steel.blogspot.co.id/2017/10/brass.html">Brass</a> is an alloy consisting of 50% or more of copper, to which zinc and smaller amounts of other elements usually tin, lean, or aluminum have been added. <a href="http://carbon-steel.blogspot.co.id/2017/10/bronze.html">Bronze</a> is a copper base alloy where tin, rather than zinc, is used). The color, strength, machine-ability, and corrosion resistance of brass are determined by the percentage of zinc and other metals present.</blockquote></div><ul><script async="" src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script> <ins class="adsbygoogle" data-ad-client="ca-pub-2260011659819468" data-ad-format="fluid" data-ad-layout="in-article" data-ad-slot="5412167182" style="display: block; text-align: center;"></ins> <script>

If not follow the result will not maximal.<br />
<br />
Condition for anodizing by your self:<br />
<ol><li>Use pure aluminum in order can get best result</li>
<li>Use pure sulfuric acid mean not contaminated by other chemicals</li>
<li>Use pure DC electric in order can get open pores of aluminum surface, for this you can take car battery, it’s depend on the current flow you need but better use current controller equipment in order can control constant current flow, current is no need too high but regular in continues flow. </li>
<li>Use <a href="http://anodizing-process.blogspot.co.id/2017/10/anodizing-dye.html">anodized dying</a> or chemicals coloring agent that already test in order get best coloring result. For this I have search in internet like Clariant also sell good product for anodized finishing. In your country could be different product.</li>
</ol><script async="" src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script><br />

<br />
If you use coloring agent from credible supplier you can ask them to get the best anodized color, as their promotion. The coloring agent that provide from Clariant are vary, for black colors and also for many other interesting colors. Sanodal for deep black MLW, sanodal Gold 4N for gold color, sanodal green 3LW for green color, sanodal orange 3LW for orange color, sanodal red B3LW for shade red color or nearly bronze color, sanodal turquoise PLW for prusian blue color.<br />
<br />
For example several colors agent produce by Clariant Chemicals as on the picture below:<br />

Currently dying agent for anodizing aluminum already provided in chemicals shop, so we don’t need any reacting chemicals to make some certain color. For example to make gold color on the surface of anodized aluminum. We just mixed with water of chemical powder for one pack can mixed with 4 liter of water (on this purpose we use distilled water). For work with one pack formula, we can use 10 liter tank volume to make sealing process of <a href="http://anodizing-process.blogspot.co.id/2008/01/aluminum-anodizing.html">anodized aluminum</a>.<br />
<br />
If you want to buy this dye agent there are many coloring agent are already provide for certain color. The price is depend on your country that may different. Just for image that the most expensive is gold color then black color, other color usually cheaper. <br />

Satisfactory nickel plate can only be obtained in the pH 5.2 to 5.8. The pH value of the <b>nickel plating solution </b>tends to rise slowly in use, due to a small proportion of current discharging hydrogen ions rather than nickel ions, especially at lower pH values of the solution, and must be adjusted from time to time by adding <a href="http://chemistry-grahito.blogspot.co.id/2009/06/sulfuric-acid.html">sulfuric acid</a>, or alternatively, if it has become too acid, by adding nickel carbonate. The presence of the boric acid in the solution ensures that these changes of pH value are less sudden than would otherwise be the case.<br />

The nickel plating solution is held in an open topped, lead lined or hard rubber lined tank. The solution is heated by immersed steam coils or electric heaters, or in some other way. A temperature of at least 35 oC is usual, but because higher current densities, and hence faster <a href="http://electroplating-process.blogspot.com/">electroplating</a>, can be achieved at higher temperatures, the bath are often operated at temperature up to 65 <sup>o</sup>C or 70 <sup>o</sup>C. The plating solution is stirred or agitated, usually by compressed air, which is blown in through a perforated pipe on the floor of the tank.<br />
<br />
The tank is provided with a central metal rod at the top, from which the articles to be plated can be hung by the wires or jigs on to which they were fixed prior to de-greasing. This rod is connected to the negative side of the low voltage direct current supply. Similar rods are arrange a long two opposite sides of the tank, and are connected to the positive side of the current supply. On these the nickel anodes are hung by metal hooks. Nickel anodes are usually cast with some care from metal containing oxide and other trace elements to facilitate their dissolution, and these are called depolarized anodes. Nickel (and other electroplating) <a href="http://electroplating-process.blogspot.com/2007/12/anode.html">anodes</a> are therefore enclosed in heavy cotton twill bags. The electric current and the solution can percolate through the fabric, but the particles are retained. It is nevertheless quite common for nickel plating solutions to be filtered continuously, or from time to time.<br />

Anodized aluminum should be finished object not raw material. If anodized aluminum as raw material the process on forming goods can injure the anodized surface. Anodized aluminum have benefits more stand to corrode and even more stand to friction. Beside this <b>anodized benefit</b>, anodized aluminum also have good color looking and make prefer to choose. <br />
<br />
<h3>How the process of aluminum oxide can be?</h3>Aluminum is a soft metal and easily corrode on the surface to form aluminum oxide. After oxidation reacted on the surface, the corrode process will stop because blocked by aluminum oxide. On the normal condition this aluminum oxide easily broke and rubbed so natural aluminum oxide can’t stand too long. After rubbed the oxide layer, then corrosion process will continue and corrode will more deeper happened.<br />
<br />
<h3>Why aluminum should be anodized?</h3>On the artificial aluminum oxide, <a href="http://anodizing-process.blogspot.co.id/2008/02/sealing-oxide-film.html">aluminum oxide film</a> can resist to friction because surface pores of aluminum oxide already closed by sealing process. On further process of anodized aluminum process, before this pores is closed, aluminum oxide can be inserted color, after the color dye enter to the aluminum oxide then the oxide film closed. Old technology can able to change the oxide film by reaction the aluminum metal below the oxide film with certain chemicals and change the color because of new chemicals form and have certain color. On modern technology the <a href="http://anodizing-process.blogspot.co.id/2008/02/mechanism-of-coloring.html">mechanism of coloring</a> is not just by reacted the surface of aluminum but by inserting color to make the surface of aluminum below oxide film is colored. To make coloring happened on this process by conditioning the dying agent molecule must smaller than the pores of oxide film hole. By <a href="http://anodizing-process.blogspot.co.id/2008/02/sealing-oxide-film.html">sealing process</a> this oxide film is stronger than nature oxide film, this make anodized aluminum more resist to corrode as long as the oxide film not broken.<br />
<br />
<h3>Where you can make anodized aluminum?</h3>You can do this process at your home, or laboratory for small experiment. For big project you must find-out some anodized aluminum service. Some small organization of anodized aluminum service also available and accept for small part to be anodize and usually also serve of raw material purchase. Anodizing of aluminum actually is not a difficult matter and you can do on your small lab at your home. You just need to provide DC current source like car battery and some chemicals that already sold in Autoshop’s spare part, solution to fill wet <a href="http://mobileandmotor.blogspot.co.id/2008/01/battery.html">car battery</a>, that have chemicals name <a href="http://chemistry-grahito.blogspot.co.id/2009/06/sulfuric-acid.html">sulfuric acid</a>.<br />

<h3>When you must anodized aluminum?</h3>After you make some part from aluminum metal you should be anodized the part before its being corrode and change the surface color become bad look with white spots. In order get good result of anodized aluminum, you must use pure aluminum, more high purity will result better anodized aluminum, but more pure aluminum metal will be more soft.<br />

The scripted is made by John Ayres, in 1683. Copperplate script is calligraphy handwriting in beautiful written. Calligraphy word itself is may derived from Greek for beauty (kallos) and write (graphein). Most calligraphy is made by pen and ink on paper or parchment, but for the time being this calligraphy already made by engine like computer or printing industries.<br />
