Prevents aluminum alloy from oxidizing and increases the durability and wear resistance of its surface.
Generally, aluminum alloys are easy to oxidize. Although the oxide layer has a certain passivation effect.
However, as a result of long-term exposure, the oxide layer will still peel off and lose its protective effect.
Therefore, the purpose of anodic treatment is to use its easy oxidation characteristics to electrochemically
generate an oxide film to prevent further oxidation of the aluminum material and increase the mechanical
properties of the surface. When the aluminum alloy is anodic oxidized, a layer of aluminum oxide will form
on the surface. Since aluminum oxide is a very hard material, its wear resistance is increased. It is commonly
used for the surface treatment of parts that need to be frequently moved and rubbed against each other, such
as pistons, valves, cylinder liners, and other hard, wear-resistant, and highly corrosion-resistant aluminum alloy parts.
Anodic oxidation is generally more commonly used in primary colors or black. With the improvement of market
requirements for appearance, dyeing is another popular application of anodic aluminum oxide. During the anodic
oxidation process, a porous oxide layer is formed on the surface of the aluminum alloy. The structural characteristics
of the oxide film can be used for dyeing, dyeing into various bright colors to meet the needs of appearance diversity.
Alumina has high chemical stability and relatively low electrical conductivity. It has high insulation strength, high resistivity,
and low dielectric loss. It can be used in electric vehicle battery terminals, insulators, integrated circuit substrates, cable pins, etc.
A material protection technology that forms a film on the surface of a metal material that acts as an anode in a specific electrolyte
by applying an external current. Most metal materials (such as stainless steel, zinc alloy, aluminum alloy, magnesium alloy, copper
alloy, titanium alloy) can be anodic oxidized in a suitable electrolyte.
Anodic oxidation is a method of changing the surface chemistry of metals and other substrates. It prevents corrosion, enhances
aesthetics, resists scratches, and is one of the most durable surface treatments available. There are three common anodic oxidation
processes for precision mechanical parts: chromic acid anodic oxidation, sulfuric acid anodic oxidation, and hard anodic oxidation.
