BATHS FOR ELECTRODEPOSITION OF TERNARY ALLOYS

摘要

Bright, tarnish resistant and color stable ternary alloys of about 40-90% of tin, about 10-50 % cobalt and about 1-28% of a third metal of Periodic Group IIIA or VIB. Typical third metals are zinc or antimony. The alloys are electrodeposited from aqueous acidic baths at a temperature of about 50-85.degree.C. and current density of about 5-45 A/ft2.
