Abstract

PURPOSE: To provide superior corrosion resistance even to a thin gold plated film by dipping a product, in an aq. alkaline chromate soln., obtd. by plating a silver base material with gold followed by electrolysis using the product as a cathode.
CONSTITUTION: A product obtd. by plating a silver base material with gold is dipped in an aq. alkaline chromate soln. of pH≥9 pref. contg. phosphoric acid or a phosphate followed by electrolysis using the product as a cathode at a current density of 0.3W0.5 A/dm2 for 1W5 min. By this method formation of a corrosive film can be prevented even in case of a gold plated film with such a small thickness as 1W3 μ.
