Product Description

Aluminum alloy phosphoric acid anodizing is an electrochemical surface‑treatment process that uses phosphoric acid as the electrolyte to form a thin, highly porous alumina oxide film. This film does not serve as an independent protective layer; rather, it is primarily employed as a pre‑treatment step prior to adhesive bonding, electroplating, or coating, significantly enhancing the adhesion between the subsequent coating and the substrate. It is widely used in the surface preparation of aluminum components in the aerospace industry.
