| 摘 要： | 为改善PAO10体系的润滑性能，合成了一种油溶性离子液体并与T321及二氧化硅进行对比。通过同步热分析仪测试PAO10润滑体系的热稳定性；通过SRV-IV微动摩擦磨损试验机对比评价不同离子液体的摩擦学性能；通过非接触式三维轮廓仪和扫描电子显微镜对磨斑形貌和磨损体积进行了表征；通过EDS和XPS元素分析对磨斑表面化学成分和化学变化进行分析。结果表明合成的油溶性离子液体可以显著提高PAO10体系的热稳定性，且无论在常温还是高温下，都具有优异的减摩抗磨性能，并极大地提高了PAO10体系的极压承载性能。通过实验结果推测极性元素P、S在摩擦过程中发生摩擦化学反应，生成的摩擦化学膜有效地抑制摩擦副之间的直接接触，提高了PAO10体系的减摩抗磨性能。

| Abstract: | In order to improve the lubrication performance of PAO10 system, an oil-soluble ionic liquid was synthesized and compared with T321 and silica. The thermal stability of PAO10 lubrication system was tested by a synchronous thermal analyzer. The tribological properties of different ionic liquids were compared and evaluated by the SRV-IV fretting friction and wear tester. The wear scar morphology was measured by a non-contact three-dimensional profiler and a scanning electron microscope and the wear volume were characterized. The chemical composition and chemical changes of the wear surface were analyzed by EDS and XPS element analysis. The results show that the oil soluble ionic liquids can significantly improve the thermal stability of PAO10 system. It has excellent anti-friction and anti-wear properties no matter at room temperature or high temperature, and greatly improves the bearing capacity of PAO10 system. XPS analysis results show that the tribochemical reaction of polar elements P and S occurs in the friction process, and the tribochemical film formed can effectively inhibit the direct contact between the friction pairs, and improve the friction reducing and anti-wear performance of PAO10 system. |
