摘　　要：以不锈钢为基体材料,Ni-W-P为基质合金,添加耐磨微粒碳化硅(SiC)和六方氮化硼(-αBN)固体润滑微粒,在抛光轮工作面镀制Ni-W-P/SiC+BN多元复合镀层。该工艺得到的Ni-W-P/SiC+BN多元复合镀层表面光亮、质感均匀、镀层结合力良好、耐蚀性优良。经过相同次数磨损试验,Ni-W-P/SiC+BN热处理镀层的耐磨性能是0Cr18Ni9Ti不锈钢的5.22倍。In order to strengthen wear resistance of bull wheel surface, the composite plating was applied. Stainless steel was taken as the base material and Ni-W-P alloy as host alloy, adding SiC and BN particle in the composite coating, Ni-W-P/SiC＋ BN multivariant composite coating was perpared. The surface with the muhivariant composite coating was bright and homogeneous. The cladding material bond was fine. Corrosion-resistance was good. Abrasion test showed that the wear resistance with coating was 5.22 times that of stainless steel.
