What will happen to aluminum after anodizing ~！！！！！
Jul 09, 2022
Aluminum or aluminum alloy products as the anode, placed in electrolyte solution for electricity treatment, the use of electrolysis to make the surface of the formation of alumina film process, known as the anodic oxidation of aluminum and aluminum alloy. After anodic oxidation treatment, aluminum surface can form several microns - several hundred microns of oxide film. Compared with the natural oxide film of aluminum alloy, its corrosion resistance, wear resistance and decoration are obviously improved and improved.
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 becomes an indispensable link in the use of aluminum alloy. Metal oxide film changes the surface state and performance, such as surface coloring, improve corrosion resistance, enhance wear resistance and hardness, protect the metal surface.
