What Are the Oxidization Methods of Aluminium Discs Circles
In our daily life, the use of aluminium discs circles are widely used. The oxidization methods is an important way to extend its life. What are these oxidization methods?
1. Natural Oxidation
The oxide film formed by this aluminum oxidation treatment is relatively thin, and the thickness is usually between 0.5 μm and 4 μm. In addition, the oxidation process is porous and has a softer texture. Although this aluminum oxidation treatment method has good adsorption performance, its corrosion resistance and wear resistance are not as good as other methods.
2. Electrochemical Oxidation
The thickness of the oxide film formed after the aluminum oxidation treatment is generally 5-20 microns, and the hardness can be improved to a certain extent. In addition, it can form relatively good insulation performance and heat resistance, and the corrosion resistance produced is better than chemical oxide film.
3. Chemical Oxidation
This aluminum oxidation treatment device is advanced, of high efficiency and wide application and easy to operate. It ha no limitation for the size of the aluminum circles.
This aluminum oxidation process is to put aluminum circles into the relevant electrolyte. Then, under the action of the current, an oxide film is formed on the surface of the aluminum discs. This is one of the most commonly used methods.
The electrolytes with different concentrations can help to better control the process conditions in the oxidation process, so that the performance of most aluminum materials can be significantly improved and improved.
