    摘要: A solution for use in electroplating which comprises at least one monovalent metal such as copper, silver or gold which is complexed by a thiosulfate ion; and a stabilizer of an organic sulfinate compound such as, for example, one having the formula R-SO.sub.2 -X wherein R is an alkyl, heterocyclic or aryl moiety and X is a monovalent cation. The stabilizer is present in an amount sufficient to stabilize the thiosulfate ion when the solution is operated at an acidic pH of less than 7. Also, the solution is substantially free of cyanide.

    摘要: 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.
