| Abstract: |
| in this paper, the composite coating of Ni/nano SiC was prepared by brush-plating technology. Its microbardness and tribological properties were examined, and the relationship between the main parameters and above properties were discussed. The test results showed that nano-SiC particles could enhance obviously the hardness of coating, and its friction coefficient was lower than that of Ni coating, and displayed a decreasing tendency when the concentration of nano-SiC and additives in the solution were increased. An evident improvement in wear resistance of composite coating was observed. Optical microscope (OM) and electron probe micro-analyzer (EPMA) were employed to analyze the microstructure, surface morphology and elements distribution of the composite coatings. Based on the experiment results, the mechanism of co-deposition of nano-SiC and Ni was discussed as well. |
