Red plague copper
Web19. dec 2000 · They established that “redplague” originates at breaks in the silverplating of copper wire strands in the presence of moisture and oxygen. The environmental test system artificially promotes “redplague” corrosion under controlled laboratory conditions as a result of galvanic corrosion of the copper conductor core. WebIt forms on silver -plated copper parts exposed to moisture when the silver layer is porous or damaged. This kind of corrosion is known as red plague . Little evidence exists for copper (I) hydroxide CuOH, which is expected to rapidly undergo dehydration. A similar situation applies to the hydroxides of gold (I) and silver (I). Properties [ edit]
