| Abstract: |
| In order to make the nano-composite coating with high micro-hardness and high corrosion resistance, Ni-based coating with nanometer WC particles was made on 18-8 stainless steel substrate. The surface morphology of the composite coating was observed, the micro-hardness and corrosion resistance of the composite coating were measured. The experiment results show that the composite coating has a smooth surface, and its micro-hardness is remarkably improved as compared with that of stainless steel or pure nickel coating, its corrosion resistance is about 4 times to that of stainless steel, but a little low than pure nickel coating. |
