Abstract
Ni-SiC nano composite coatings were prepared on pure copper substrate. The surface morphology and distribution of nanometer particles of the composite coatings were observed by scanning electron microscope (SEM), micro-hardness of coatings was tested by HXD-1000 microharder. The results showed that microstructure of Ni-SiC nano composite coating is different from that of electrodeposited nickel coatings. Its electrodepositing process abided by the principal of adsorption. By adding nanometer particles, the structure of composite coatings can be effectively fined, microhardness of composite coatings is improved apparently by comparing with that of electrodeposited nickel coatings. Abrasion resistance of Ni-SiC nano composite coatings is excellent.
