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 electrical circuit. Anodizing increases corrosion resistance and wear resistance, and provides better adhesion for paint primers and glues than does bare metal. Anodic films can also be used for a number of cosmetic effects, either with thick porous coatings that can absorb dyes or with thin transparent coatings that add interference effects to reflected light.Anodizing is also used to prevent galling of threaded components and to make dielectric films for electrolytic capacitors.
