An electrolytic process that coats metal with a protective or decorative film; used primarily with nonferrous metals, principally aluminum.
The process is called anodizing because the part to be treated is the anode of the electrical circuit used for the process.
Anodizing increases corrosion resistance and wear resistance, and provides better adhesion for paint primers and glues than does bare metal.
