High Performance Electrolytic Coating Touch-Up Repairs for Aluminum

Corrosion protection for aerospace aluminum primarily relies on two inorganic coatings: chromate conversion coating and anodize coatings. Anodizing provides a superior barrier against corrosion, especially in harsh salt-water environments. In contrast, chromate conversion coatings (e.g., Alodine, Iridite) offer less protection but are significantly easier to apply, requiring a simple, non-electrolytic chemical application.

This difference in application creates a maintenance challenge. Anodizi...
