ABSTRACT:
An electroplating bath, a system, a process for, and the article obtained from, depositing a zinc-nickel ternary or higher alloy, a) zinc ions; b) nickel ions; and c) one or more ionic species selected from ions of Te+4, Bi+3and Sb+3, and in some embodiments, further including one or more additional ionic species selected from ions of Bi+3, Sb+3, Ag+1, Cd+2, Co+2, Cr+3, Cu+2, Fe+2, In+3, Mn+2, Mo+6, P+3, Sn+2and W+6. In some embodiments, the system includes a divider forming a cathodic chamber and an anodic chamber, with the electroplating bath in the cathodic chamber only. In various embodiments, the zinc-nickel ternary and higher alloys may provide improved properties to the conductive substrates upon which the alloys are deposited.
