What is the common treatment used on aluminum to prevent oxidation?

The surface of the aluminum alloy chassis is easily oxidized, resulting in a very thin aluminum oxide film. This oxide film is not only loose and porous but also uneven, and the corrosion resistance is not strong. It is easy to be stained, thus affecting the aluminum alloy. The beautiful appearance of the chassis.

The method to solve the oxidation spots of aluminum alloy chassis:

1.?We can use an alkaline solution for cleaning so that the oxide film adsorbed with dirt can be removed. After the oxide film is removed, they washed the aluminum alloy chassis several times in distilled water. Finally, it was boiled in distilled water to seal the pores in the oxide film. In this way, the surface of the aluminum alloy after cleaning will generally not be adsorbent with spots.

2. They can soak the aluminum alloy chassis in dilute acid or dilute alkali. When there is gas, take out the aluminum alloy chassis immediately, and then wash it with water. You can also use sandpaper to sand the spots to restore them. You can also use rosin to clean the speckled aluminum alloy.

3. Before the oxidation treatment of the aluminum alloy chassis, the surface of the product should be cleaned by chemical and physical methods to expose the pure metal matrix, which is conducive to the smooth progress of oxidation and coloring, to get a firm bond with the matrix, and the color and thickness requirements are satisfied. Artificial membranes are required and have the best corrosion resistance, wear resistance, and other good properties.

4. We should perform mechanical polishing on the end face produced by wire cutting. After the molybdenum wire is energized, we generate an electric spark to burn off the aluminum metal, and the aluminum oxide layer left on the surface is removed.
