The process of using aluminum or aluminum alloy products as anodes, placing them in an electrolyte solution for electrification treatment, and using electrolysis to form an aluminum oxide film on the surface is called anodizing of aluminum and aluminum alloys.
After anodizing, an oxide film of several microns to hundreds of microns can be formed on the aluminum surface. Compared with the natural oxide film of aluminum alloy, its corrosion resistance, wear resistance and decorative properties are significantly improved.
