摘要	In order to reduce the friction coefficient of a pure nickel coating and extend the lifetime of metal parts under extreme friction conditions, a series of Ni-based WS2-composite solid lubrication coating containing different WS2 concentrations were prepared on a 45# mild carbon steel substrate by electroplating. The cyclic voltammetry method was used to investigate the electroplating regulation of the Ni-WS2 composite coatings. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to analyze the microstructures and wear surfaces of the composite coatings, the tribological properties and wear mechanisms of the composite coatings with different WS2 concentrations. The results show that the addition of WS2 can promote the cathode polarization of the electroplating process, and the polarization degree goes up with the increase in WS2 concentrations. The friction coefficient of Ni-composite coatings significantly decreases by the addition of WS2 particles. The lowest friction coefficient at room temperature is obtained at a value around 0.01-0.03 from the coating deposited in the electrolyte solution with a 30 g.L-1 WS2 concentration. The friction coefficient of the Ni-WS2 composite coating remains in 0.01-0.03 with the increase in temperature from room temperature to 300 degrees C. When the temperature goes up to 500 degrees C, the friction coefficient manifests a continuous increase to 0.12, because WS2 is gradually oxidized into WO3 and therefore loses its lubrication ability.
