Abstract
An electrical terminal is disclosed where the terminal is formed of an electrically-conductive metal substrate such as copper alloys, aluminum alloys or stainless steel with the substrate having a codeposited composite coating of titanium nitride and gold or silver on the surface. The coating provides wear resistance in high temperature and vibration environments while retaining and demonstrating low friction and low contact resistance properties.
