Abstract
Alkaline cyanide-free copper strike baths are provided for the purposes of electrodepositing a copper-zinc alloy strike coating unto a metal based substrate so as to prevent immersion coating by the copper on the metal substrate and thereby provide a basis for the subsequent addition to the substrate of composite electrodeposits which are blister free and highly adherent. Electrochemical coating processes for employing such strike baths and the resulting products are disclosed.
