| 摘要 |
There is provided a composite plated product which has a large content of carbon and a large quantity of carbon particles on the surface thereof and which has an excellent wear resistance, by sufficiently dispersing carbon particles in a silver plating solution without using any additives such as dispersing agents and without coating the surface of carbon particles. A wet oxidation treatment for carbon particles is carried out by adding an oxidizing agent to water in which the carbon particles are suspended, and the carbon particles treated by the wet oxidation treatment are added to a cyanide containing silver plating solution for electroplating a substrate to form a coating of a compositematerial, which contains the carbonparticles in a silver layer, on the substrate. |
