摘要
由于加入了脆性的CaF2 而使材料的机械性能稍有下降 ,在室温、载荷 5 0N、滑动速度 1 5m/s的情况下使材料的磨损率下降 2 8% ,在 6 0 0℃时下降 4 0 4 %。对 4 #材料在不同温度下的摩擦磨损性能分析结果显示 :随着温度的升高 ,材料的摩擦系数逐渐减小 ,材料的磨损率先减少后升高。载荷对材料的摩擦系数影响很小 。
The tribology of the high temperature self lubricating alloy (CaF 2/Ni(Cr,Cu))has been improved because of the CaF 2 added The wear rate of CaF 2/Ni(Cr,Cu)decreases by 28% at room temperature and 40 4% at 600℃ respectively when added with 15wt% CaF 2 With analyzing the 4# material the friction coefficient decreases with the increasing of the temperature,the wear rate of the material decreases at first and increases then The loading on the specimen has only a slight effect on the friction coefficient but increases the wear rate of the material
