Abstract
PURPOSE: To enable high-speed silver plating without newly constructing facilities by carrying out silver plating with a silver plating soln. contg. specified amounts of silver cyanide and potassium cyanide at a specified current density.
CONSTITUTION: By providing a composition contg. 75.0W106.0g/l silver cyanide and 90.0W139.0g/l potassium cyanide to a silver plating soln. and regulating the current density to about 1.5A/dm2, plating having about 30μm thickness is obtd. in about 30W35min plating time, and the silver plating stage can be reduced to about 1/3 of a conventional stage. By adding about 0.05W0.15g/l sodium thiosulfate, the plated surface can be made bright.
