摘　　要：研究了将粒径约为 4 0nm的纳米碳酸钙粒子作为添加剂加入 4 0CD润滑油中 ,采用四球摩擦磨损试验机测定含纳米碳酸钙粒子的润滑油的摩擦学性能 ;利用扫描电子显微镜、X射线光电子能谱仪观察与分析磨斑表面形貌、元素的状态等。结果表明 ,含 0 .6 %纳米碳酸钙的润滑油具有最佳的抗磨减摩性能 ;文中对抗磨减摩机理进行了探讨。The morphology and size of the CaCO 3 nanoparticles were examined by transmission electron microscope (TEM). The lubricating oils with CaCO 3 nanoparticles were prepared. The tribology tests were carried out in four-ball tribotester. The surface morphology and chemical element states have been tested and analyzed by scanning electron microscope(SEM) and X-ray photoelectron spectrum(XPS). The research results show that the lubricating oil with 0.6% CaCO 3nanoparticles has optimum properties of friction-reduction and wear resistance.The mechanism of friction-reduction and wear resistance was discussed.
