Copper plating steel Bladesmith 39s Forum Board

Copper is more noble then steel, which means that copper on it 39s own will not corrode as fast as steel. But when copper plated steel gets exposed, then the steel will become the anode, and the reverse will happen: the steel will protect the copper by rusting away, and rusting faster then if it weren 39t copper plated.
