Peel Off Problem from Bright Cobalt Plating


2000

A Bright Cobalt is plated on copper using a cobalt chloride bath. However, the plating is peel off after salty test or ammonia test. Is it because of the high internal stress? If yes, any additive can be used to reduce the internal stress.

That could be. Yes, there are many additives that will reduce stress in cobalt plating. In nickel plating, high chloride has been associated with higher tensile stress of the deposit.
