| Abstract: | The effects of SiC concentration in electrolyte, cathodic current density, stirring rate, pH value and temperature on SiC content in Ni-SiC nano-composite coating and codeposition rate are analyzed. The optimized process parameters are obtained by orthogonal test, and the surface morphology and energy spectrum of the Ni-SiC nano-composite coating are also analyzed. The results show that the Ni-SiC nano-composite coating has a flat morphology and compact microstructure, and its micro-hardness is remarkably improved as compared with that of pure nickel coating. |
