在四球摩擦磨损实验机摩擦区域添加了直流磁场发生装置,研究了添加经修饰的纳米WS
2
润滑油在直流磁场作用下的摩擦磨损性能,用扫描电镜(SEM)配合能谱仪(EDS)及X射线光电子能谱仪(XPS)对钢球磨斑区域表面形貌和典型元素的含量及化学状态进行了分析,并探讨了相关的摩擦学机理。实验结果表明:经修饰后的纳米WS
2
在150SN基础油中稳定性良好,含纳米WS
2
的润滑油体现出更好的润滑性能,在纳米WS
2
含量相同时,直流磁场下的润滑油抗磨减摩效果更好。直流磁场对纳米WS
2
有一定的聚集效应,并会提高摩擦化学反应发生的概率。
A DC magnetic field generator was assembled around the friction region in a four-ball tester. The tribological properties of 150SN base oil and lubricating oil containing modified nano-WS
2
under and without DC magnetic field were studied by modified tribo-tester. The morphology
the content and chemical species of typical elements on the worn surfaces lubricated with the tested oil were examined by SEM-EDS and XPS
and then the tribological mechanism was discussed.
The results indicate that the modified nano-WS
2
has good stability in 150SN base oil. The lubricating oil containing nano-WS
2
exhibits better lubrication performance. In addition
when the nano-WS
2
content is the same
the anti-wear and friction reduction effect of the lubricating oil under DC magnetic field is better. The DC magnetic field had a certain aggregation effect on nano-WS
2
and could increase the possibility of tribochemical reaction.
