We investigated composite plating of Ni-WC using pulse current electrolysis with surfactants having an azobenzene group (AZTAB). The WC content of Ni/WC plating using 1 μm WC particles increased with increased pulse frequency from 15 vol.% to 25 vol.%. This value increased to more than 50 vol.% for 40−70 nm WC particles. Roughness of the plating using 1 μm WC particles decreased from 8 μm to 2 μm with increased pulse frequency. This value decreased to 1.5 μm for WC 40−70 nm particles. The hardness and wear resistance of these platings were compared.
