BIMETALLIC ZINCATING PROCESSING FOR ENHANCED ADHESION OF ALUMINUM ON ALUMINUM ALLOYS |
| 摘要 |
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. |

1. A coated metal component comprising:
an aluminum alloy substrate; an intermediate layer on the substrate comprising isolated islands of a first metal deposited on the aluminum alloy substrate, wherein the first metal is capable of electroless co-depositing with zinc; and an electrodeposited aluminum protective coating on the intermediate layer and aluminum alloy substrate. |
