Title:
複合めっき材の製造方法
Document Type and Number:
Japanese Patent JP4862192
Kind Code:
B2
Abstract:
There is provided a method for producing a composite plated product wherein a coating of a composite material containing carbon particles in a silver layer is formed on a substrate by using a composite plating solution wherein carbon particles treated by an oxidation treatment and a silver matrix orientation adjusting agent are added to a silver plating solution, the method being capable of preventing the wear resistance of the composite plated product from being deteriorated even if the current density in a plating process is increased. The molar ratio of silver to free cyanogen in the composite plating solution is adjusted so as not to be less than 0.7, preferably so as to be in the range of from 0.7 to 1.3. The silver matrix orientation adjusting agent contains selenium ions, and is preferably potassium selenocyanate. The concentration of the silver matrix orientation adjusting agent in the composite plating solution is adjusted so as to be in the range of from 5 mg/l to 20 mg/l.
