通过高能球磨、冷等静压及高频感应烧结在Ni基合金圆棒上成功制备HFIS304高温自润滑涂层.HFIS304成分(质量分数,下同)为NiCr (80/20)合金(60%),Cr_2O_3(20%),Ag(10%)和共晶BaF_2/CaF_2 (10%).HFIS304涂层组织致密,3种润滑相尺寸细小.研究表明,在室温到600 ℃的范围内,HFIS304涂层的耐磨性优于PS304涂层.
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 Cr_2O_3 (20wt%), Ag (10wt%) and eutectic BaF_2/CaF_2 (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.
