Anodizing

In order to overcome the defects of surface hardness and wear resistance of aluminum alloy, expand the application range and prolong the service life, surface treatment technology has become an indispensable part of the use of aluminum alloy, and anodizing technology is the most widely used and most successful. of.
Definition of anodic oxidation: electrochemical oxidation of a metal or alloy.
Principle The metal or alloy article is used as an anode, and an oxide film is formed on the surface by electrolysis. Metal oxide films alter surface conditions and properties such as surface coloration, improved corrosion resistance, enhanced wear resistance and hardness, and protection of metal surfaces. For example, aluminum anodization, aluminum and its alloys are placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as an anode, and electrolysis is carried out under specific conditions and an applied current. The aluminum of the anode or its alloy is oxidized, and a thin layer of aluminum oxide is formed on the surface, and the thickness thereof is 5 to 20 μm, and the hard anodized film is 60 to 200 μm. The anodized aluminum or its alloy improves its hardness and wear resistance up to 250-500 kg/mm ​​2 , good heat resistance, and the hardness of the hard anodized film is as high as 2320 K. It is excellent in insulation and resistant to attack. The wearing voltage is up to 2000V, which enhances the corrosion resistance and does not corrode in the salt fog of ω=0.03NaCl for several thousand hours. The oxide film has a large number of micropores in the thin layer, which can adsorb various lubricants, and is suitable for manufacturing engine cylinders or other wear-resistant parts; the film microporous adsorption ability can be colored into various beautiful and beautiful colors. Non-ferrous metals or alloys thereof (such as aluminum, magnesium and their alloys) can be anodized. This method is widely used in mechanical parts, aircraft parts, precision instruments and radio equipment, daily necessities and architectural decoration.
Other types of supplementation: in addition to metals, the oxidation of other substances at the anode, also known as "anodizing"

Supplement: In the actual process, the anodizing of aluminum alloy is more, it can be applied in daily life, thinking that the characteristics of this process make the surface of aluminum parts have a hard protective layer, which can be used for the production of daily necessities such as kitchen utensils. However, the anodizing effect of cast aluminum is not good, the surface is not good, and it can only be black. The aluminum alloy profile is better.
Supplementary content Electrochemical oxidation of metals or alloys. A metal or alloy article is used as an anode, and an oxide film is formed on the surface by electrolysis. Metal oxide films alter surface conditions and properties such as surface coloration, improved corrosion resistance, enhanced wear resistance and hardness, and protection of metal surfaces. For example, aluminum anodization, aluminum and its alloys are placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as an anode, and electrolysis is carried out under specific conditions and an applied current. The aluminum of the anode or its alloy is oxidized, and a thin layer of aluminum oxide is formed on the surface, and the thickness thereof is 5 to 20 μm, and the hard anodized film is 60 to 200 μm.

Why anodizing:

In order to overcome the defects of surface hardness and wear resistance of aluminum alloy, expand the application range and prolong the service life, surface treatment technology has become an indispensable part of the use of aluminum alloy, and anodizing technology is the most widely used and most successful. of.

What is the anodization of aluminum:

The so-called anodization of aluminum is an electrolytic oxidation process in which the surfaces of aluminum and aluminum alloys are usually converted into an oxide film which has protective, decorative and some other functional properties. The anodization of aluminum from this definition includes only the part of the process of forming an anodized film.
