Anodic coating improves the surface corrosion protection of aluminum under severe service conditions. This coating also serves as a base for paint. Anodic coatings provide better corrosion protection that chromate chemical conversion coatings.

Hard anodic coatings improve wear and abrasion resistance of aluminum alloys. Dyeing and/or sealing are not recommended unless corrosion resistance is not required. These steps reduce wear resistance of hard coat.
