Also known as the Boeing process, PAA is recognized as an excellent preparation for adhesive bonding in the aerospace industry. The oxide film formed during the anodizing process has greater durability under adverse conditions than films formed in chromic acid anodizing (CAA) and sulfuric acid anodizing (SAA). The ASTM D3933 specification describes the PAA for bonding applications.
