摘　　要：研究了一种纳米矿物润滑油添加剂在改装的摩擦试验机上对钢／钢摩擦副表面改性的影响及作用机理，采用扫描电镜、X射线能量色散谱仪、显微硬度测试仪等对摩擦表面形成的保护层进行了分析，结果表明，摩擦试样表面有添加剂物质沉积膜生成，表面微区增添了来自矿物粉体中的元素，显微硬度显著提高，对摩擦表面起到了很好的减摩作用.Tests the effect of an inorganic material as lubricating additive. The test investigates the influence and mechanism of the additive on the steel/steel friction pair in the improved friction apparatus. Furthermore, SEM, EDS and microhardness tester are used to analyze the inorganic repaired layer formed on the friction surface. Based on the test result, it is found that the additive creates certain deposited film on the friction surface. Elements of the inorganic material are added on the surface. Another test result shows that the mierohardness greatly increased and the inorganic additive has obvious anti-wear effect for the steel/steel friction pair.
