Abstract
The invention described provides a process for direct electroplating on activated surfaces substantially without the formation of a smut layer and thereby improving the adhesion of the plated deposit to the surface. The use of divalent or tetravalent sulfur compounds and/or cathodic electrocleaning is proposed between activation of the surface and electroplating of the surface.
