ANODIZING

Anodizing, or anodising, is an electrolytic passivation process used to increase the thickness and density of the natural oxide layer on the surface of metals. The process derives its name from the fact that the part to be treated forms the anode portion of an electrical circuit in this electrolytic process. Anodizing increases corrosion resistance and wear resistance, and provides better adhesion for primers. As part of the process, it is possible to give the treated parts a desired decorative appearance by using organic dyes, which make it possible to impart a wide spectrum of colors to the treated surface. Since the anodizing process is a reinforcement of a naturally occurring oxide process, it is non-hazardous and produces no harmful or dangerous by-products.
