Abstract: MoS2/Ni composite film was prepared by magnetron sputtering method on the surface of 20CrMnTi base. X-ray diffraction (XRD), X-ray energy dispersive spectroscopy (EDS) and scanning electron microscopy (SEM) were used to analyze the phase composition and microstructure of the film. The friction and wear behavior was tested with the UMT-2MT tribometer. Results reveal that the composite film was integrated and regular with a homogeneous structure. This composite film had a low fiction coefficient, a nice abrasive resistance, inoxidizability and strong carrying ability, and displayed good performance when rubbed at high rotation rate.
