| Abstract: | The Ni SiC composite coating is obtained with the electrodeposition method.The thermal stability of the Ni SiC composite coating at 850℃ is studied.The corrosion resistance of the steal substrate,the Ni coating and the Ni SiC composite coating are compared by using the polarization curve.The results show that SiC won't dissociate when the temperature is at 850?℃ for 30 minutes.The corrosion resistance of the Ni SiC composite coating is better than that of Ni coating,and both of them is better than the steal substrate. |
