Electroplating calculation
WebWhat Is Electroplating? Electroplating is the process of using electrodeposition to coat an object in a layer of metal (s). Engineers use controlled electrolysis to transfer the desired … WebPlating is done by following a quantity called amperage which indicates the total amount of current that has passed through a plating bath. A change in bath’s resistance will change amperage. The amount of metal deposited depends on three factors: Amperage, Plating time, Current efficiency of the bath-Ampere-time x C.E. = mg of metal deposited
