Electroplating of Compound Ni–SiC Coatings and Improvement of Wear Resistance


Article Preview

Ni-SiC nano-composite coatings with various contents of SiC nano-particulates were prepared by means of the conventional electrodeposition in a nickel-plating bath containing SiC nano-particulates to be co-deposited. The surface morphology and structural constituent in the electrolyte layer were observed by SEM and EDS. The dependence of SiC nano-particulates amount in the nano-composite coatings was investigated in relation to the SiC concentration in bath. The effect of SiC nano-particulate incorporation content on micro-hardness as well as wear-resistance was studied too. The results showed that the nano-Ni-SiC plating layer had smooth and flat surface, uniform microstructure as well as higher micro-hardness and wear-resistance than pure Ni coating. The optimum experimental parameters were derived at condition of, addition of 6g/L SiC nano-particulates in the bath, 40°C temperature, current density of 4A/dm2 , and a stirring rate of 250rpm.
