Anodizing - Wikipedia
Anodizing - Wikipedia

Anodizing, is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.. The process is called ,anodizing, because the part to be treated forms the anode electrode of an electrolytic cell.,Anodizing, increases resistance to corrosion and wear, and provides better adhesion for paint primers and glues than bare metal does.
