Abstract

After CNTs were purified, Ni-P/CNTs composite coating were prepared at different CNTs contents and plating solution pH values by univariate experimental method. Besides, the surface appearance, hardness, corrosion resistance and wear-resisting property of the coating were tested and analyzed by X-ray Diffractometer (XRD), scanning electronic microscope (SEM), microhardness tester, electrochemical workstation, tribometer and other means. The results suggest that fibers on the surface of purified CNTs are clear and well-dispersed. During dummy-plating, purified CNTs were more likely to deposit on Ni-P coating. a proper amount of CNTs could reasonably improve the structure of Ni-P/CNTs composite coating; different pH values would lead to different specific gravities of alloying elements and CNTs deposition, and a reasonable pH value would help the coating reach the optimal hardness, wearability and corrosion resistance. In general, Ni-P/CNTs composite coating has the best comprehensive performance when the CNTs content is 40mg/L and pH value is 6.
