高温固体润滑材料在极端操作条件下的移动机器组件的应用中显示出重要的需求。研究了一种镍基自润滑复合材料（82.5% Ni-Alloy-12. 5%Ag-5%BaF2/CaF 2）与Si 3 N4球在不同温度和滑动速度下的摩擦学行为。结果表明，复合材料的摩擦系数和磨损率与试验温度和滑动速度有很大关系。该复合材料在25 °C ~ 800 °C的较宽温度范围内表现出良好的润滑性能。通过对磨损表面的观察和分析，探讨了摩擦磨损机理。
High temperature solid lubricating materials show important demands in applications for moving machine assemblies under extreme operating conditions. In this study, the tribological behavior of a nickel-alloy based self-lubricating composite (82.5%nickel-alloy–12.5%Ag–5%BaF2/CaF2) against Si3N4ball was evaluated under various temperatures and sliding speeds. Results showed that the friction coefficient and wear rate of the composite were greatly dependent on testing temperature and sliding speed. The composite exhibited favorable lubricity in the wide temperature range from 25 °C to 800 °C. The friction and wear mechanisms were explored by observing and analyzing the worn surfaces.
