摘　　要：本文研究了通过热压法制备得到的含硫镍基合金与YJ2硬质合金对偶的摩擦特征。结果表明 :在高温摩擦过程中 ,材料中的硫化物共晶体是主要的润滑组元 ,摩擦面的温度对其润滑效果有较大的影响 ;材料与YJ2对偶时的摩擦系数随着温度变化有所不同 ,但是磨损率都随着温度升高而增大 ,其高温下磨损形式主要为磨粒磨损和氧化磨损 ;The tribological characteristics of a nickel-base composites containing sulfide made by hot pressing and sliding on the hard metal YJ2, were investigated. The results indicate sulfide eutectics are the major lubricants during high-temperature friction process and the friction temperature has a big effect on its lubrication; friction coefficients are different and wear rates increase as temperature arises; particles abrasion mixed with oxidation abrasion is the dominant wear type at high temperature; oxides formed on the surface of YJ2 hard metal have great effects on the anti-friction performances.
