Abstract
A coated metal component includes an aluminum alloy substrate and a protective aluminum coating on a substrate. An interfacial boundary layer between the coating and substrate enhances coating adhesion. The boundary layer includes isolated regions of copper or tin produced by a double zincating process. The protective aluminum coating exhibits improved adhesion and is formed by electrodeposition in an ionic liquid.
