摘要：

HFIS304 self-lubricating coating was prepared by high-energy ball milling, cold isostatic pressing and high-frequency induction sintering (HFIS) on a Ni-based superalloy rod, and its composition was NiCr (80/20) matrix (60wt%) combined with Cr2O3 (20wt%), Ag (10wt%) and eutectic BaF2/CaF2 (10wt%) as solid self-lubricating additives. The microstructure of HFIS304 coating was dense, and three kinds of lubricating phases were fine. Research shows that wear resistance and friction coefficient of the HFIS304 coating are superior to that of the PS304 coating in the range from room temperature to 600°C.
