The influence of polymer additive (polytetrafluoroethylene) in grease based on paraffin oil on the resistance to fatigue wear (pitting) was investigated of rolling contact. The research results revealed that grease containing a polymer caused an increase in resistance to fatigue. It was examined whether the additive affects the properties of the grease, including rheological (investigated with the use of rheometer operated in the cone/plate configuration) and thermal (determined using the Differential Scanning Calorimetry) to check their relationship with a resistance to fatigue. A scanning electron microscope equipped with an energy dispersive spectrometer was used to determine if a polymer was present on wear trace. Then the sources of chemical elements were analysed with the use of X‐ray photoelectron spectroscopy to explain the improvement of resistance to fatigue. The relation between rheological properties and resistance to fatigue was shown, and the presence of polymer in friction contact was observed.

聚合物二氧化硅添加剂，可改善生态油脂的摩擦学性能，提高抗疲劳性

研究了基于石蜡油的润滑脂中的聚合物添加剂（聚四氟乙烯）对滚动接触的抗疲劳磨损（点蚀）性的影响。研究结果表明，含有聚合物的润滑脂可提高抗疲劳性。检查了添加剂是否影响润滑脂的性能，包括流变学（通过使用以锥/板配置运行的流变仪进行调查）和热学性能（使用差示扫描量热法确定），以检查其与耐疲劳性的关系。使用配备有能量色散光谱仪的扫描电子显微镜确定磨损痕迹上是否存在聚合物。然后使用X射线光电子能谱分析了化学元素的来源，以解释其抗疲劳性的提高。示出了流变性质和抗疲劳性之间的关系，并且观察到聚合物在摩擦接触中的存在。
