Aluminum or aluminum-alloy products are anodes, place in the electrolyte solution for energizing treatment, and form aluminum oxide film via electrolysis, which is known as anodic oxidation treatment of aluminum and aluminum alloy. After anodic oxidation treatment, oxidation films of several to hundreds of microns can be generated on the surface of aluminum. Compared with the natural oxidation film of aluminum alloy, its corrosion resistance, abrasive resistance and decorativeness are significantly improved.
