High Corrosion and Weather Resistant Anionic Resin Coating for 2014 T6 Aluminum Alloys Which Maintains Mirror Luster

Abstract

A new surface treatment technology for 2014 T6 aluminum alloys that exhibits not only high corrosion and weather resistance but also good mirror luster has been developed. By using this new electrode-position coating process with anion resin, the resin can preferentially permeate into cavities that are formed by dissolving of the second phase particles during a general anodizing process. In order to maintain the excellent appearance, the thickness of the anodized layer and anion resin layer was optimized to make the layers as thin as possible while keeping the high corrosion and weather resistance. Thanks to this newly developed surface treatment technology, high strength aluminum alloys featuring high corrosion and weather resistance with mirror luster are now available for industrial products.
