Corrosion resistant nickel-zinc-phosphorus coating.

摘要

Corrosion-resistant electrodeposited coating comprising a solid solution of phosphorus and nickel supersaturated with zinc, deposited on a substrate. The electrodeposited coating is formed from an electrolyte containing nickel chloride, zinc chloride and sodium hypophosphite having a nickel ion to zinc ion molar ratio between about 7:1 and about 12:1, and is deposited on said substrate at current densities of at least 0.6 A/cm<2>.
