Oxidation process of aluminum alloy frame processing
Jul 21, 2018

During the processing of the aluminum alloy frame, the coloring process is also required after the extrusion process is completed. Which mainly refers to the oxidation process. The so-called oxidation, that is, the extruded aluminum alloy frame processing profile, due to its surface corrosion resistance is not strong, must be surface treated by anodizing to increase the corrosion resistance, wear resistance and appearance of aluminum.

 

In the process of oxidation, the surface pretreatment of the aluminum alloy frame processing products is firstly carried out, usually by chemical or physical cleaning of the surface of the profile, to expose a pure substrate, in order to obtain a complete and dense artificial oxide film. . It is also possible to obtain a mirrored or matte surface by mechanical means.

 

The next step is anodizing, which mainly refers to the anodization of the surface of the aluminum alloy frame processed product under certain process conditions to form a dense, porous, strong adsorption Al2O3 film. Then, the pores of the pores of the porous oxide film formed by the anodization are closed, so that the oxide film of the aluminum alloy frame processing profile is prevented from being contaminated, and the corrosion resistance and wear resistance are enhanced.
