摘要
基于系列四球摩擦实验,分析了纳米WS_2颗粒在绿色润滑油PAO-6和菜籽油中的摩擦学性能。结果表明,在PAO-6或菜籽油中添加2.0%(w)纳米WS_2颗粒,可以显著改善润滑油的极压、抗磨和减摩性能,而且在更宽的温度、载荷和转速范围内保持良好的抗磨减摩性能。
Tribological properties of nano-WS2 particles in green lubricating oil, PAO-6 and rapeseed oil, were analyzed through a series of four-ball friction tests. Results show that adding nano-WS2 particles into PAO-6 or rapeseed oil with an optimum dosage of 2 ~ can significantly improve the extreme pressure antiwear and antifriction properties of the base oil. Furthermore, the excellent anti-wear and antifriction properties of lubricating oil having nano-WS2 particles could be maintained in a wider range of temperature, load and speed.
