ANTI-TARNISH COATING |
摘要 |
A method is disclosed for enhancing the corrosion resistance of a surface of a copper or copper alloy substrate. The method comprises depositing a metallic surface layer comprising a precious metal on a surface of the copper or copper alloy substrate by immersion displacement plating and exposing the electronic device to an aqueous composition comprising a first organic molecule comprising at least one functional group that interacts with and protects precious metal surfaces and a second organic molecule comprising at least one functional group that interacts with and protects copper surfaces. |
