摘要
研究了纳米Cu、纳米TiO2和纳米LaF3润滑油添加剂在85W／90基础油中的油溶性，比较了三种纳米润滑油添加剂在齿轮油中的应用效果，结果表明：纳米铜添加剂能够显著提高基础油的极压性能，同时具有良好的抗磨性能。采用SEM对铜纳米微粒在复合剂体系中的极压抗磨机理进行了分析，发现在摩擦过程中铜纳米微粒在表面形成沉积膜，从而表现出良好的极压抗磨性能。
The solubility of Cu nanoparticles in 85W/90 base oil, TiO2 nanoparticles and LaF3 nanoparticles were studied. The wear and friction properties of nanoparticles added to gear oils were compared. Results indicate that Cu nanoparticles could remarkably improve the extreme pressure and antiwear ability. SEM analyses reveal that a boundary film rich of Cu forms during friction process, which is contributed to the good tribological properties of Cu nanopaticles.
