Abstract

PURPOSE: To obtain a plated layer with superior luster and mechanical properties by adding Ni ions to a pyrophosphate-base gold-tin alloy plating soln.
CONSTITUTION: To a plating soln. contg. a tin pyrophosphate complex and gold ions is added 0.1W0.5g/l Ni. Ni acts preferentially on the active reaction site of a substance to be plated to reduce the activity, and uniform brigth plating is obtd. By further adding one of thiourea, ammonium thiocyanate, tartaric acid, etc. besides the Ni ions, a remarkable effect is produced in the weldability, etc. as well as the uniformity of the alloy composition.
