SACRIFICIAL COATING AND PROCEDURE FOR ELECTROPLATING ALUMINUM ON ALUMINUM ALLOYS |
摘要 |
A method of applying a protective coating with improved adhesion on an aluminum alloy component includes first pretreating the surface of a component by depositing a sacrificial protective immersion layer using a zincating or similar process. Portions of the protective immersion layer as well as portions of the underlying aluminum alloy substrate are then electrolytically etched off in an ionic liquid. A protective aluminum coating is then electrodeposited on the component in an ionic liquid |
