To investigate the effect of erucamide on the tribological properties of GCr15 steel in this study, polyurea grease is prepared with different concentrations of erucamide as additive. The tribological behavior of erucamide on the surface of GCr15 steel is studied using a reciprocating friction test. The results show that 1.5 wt% erucamide has the best tribological property and friction-induced vibration and noise suppression capability. This is attributed to the formation of a lubricating film on the transition region of the friction surface, which maintains the friction in a relatively stable state, and the maximum thickness of lubricating film is 3.91 μm.
