抛光轮耐磨复合镀层制备及其性能研究

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。

Preparation and Performance of Composite Coating with Wear Resistance on Buff Wheel

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 multivariant 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.
