Research on the wear and corrosion resistance of Ni–GO–TiC composite coating by scanning jet electrodeposition

Abstract

The Ni–GO–TiC nano-composite coating was prepared by scanning jet electrodeposition. The morphologies and microstructures of the composite coating were analyzed by FESEM and XRD, and the wear and corrosion resistance of the composite coating were studied. Studies have shown that the Ni–GO–TiC composite coating has some ridge shape structures. The addition of nano TiC and GO does not change the structure but refines the grain growth of the Ni matrix metal. Nano TiC can effectively prevent GO from agglomerating, improve the dispersion, and further enhance the wear resistance of the Ni–GO–TiC composite coating. In addition, the microhardness and corrosion resistance of the Ni–GO–TiC composite coating has also been greatly improved. The hard nano TiC reinforcement proposed in this study helps to improve the comprehensive properties of nickel-based graphene oxide composite coatings, and provides a new method reference for subsequent research on nickel-based composite coatings.
