| Abstract: | The effects of cathodic current density, bath temperature and electrode distance on the micro-hardness of Ni-SiC nano-composite coating were investigated in the present paper. The optimized process parameters were obtained by orthogonal test. Besides, the surface and the section morphology of the composite coating were also observed and analyzed with SEM. The results show that the Ni-SiC nano-eomposite coatings have a fiat surface morphology and compact microstructure as compared with that of pure nickel coating,and its micro-hardness is remarkably improved. |
