Anodizing Coating
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, wears resistance, and provides better adhesion for paint primers and glues. 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 one of the more environmentally-friendly metal finishing processes. With the exception of organic (integral color) anodizing, the by-products do not contain heavy metals, halogens or volatiles. The most common anodizing effluents, aluminum hydroxide and aluminum sulfate, are recycled for the manufacturing of alum, baking powder, cosmetics, newsprint and fertilizer or used by industrial wastewater treatment systems.
Key Attributes of Anodizing:
· Less expensive than painting with the exception of coil painted products
· Harder than PVD
· Better for high traffic areas
· Coating cannot peel off and is actually part of the metal
· Provides richer metallic appearance than organic coatings
· Unaffected by sunlight
