摘要/Abstract

摘要： 在聚脲润滑脂中添加了多种润滑脂添加剂，用MS-10型四球摩擦试验机研究不同添加剂对聚脲润滑脂摩擦磨损的感受性；利用扫描电子显微镜（SEM）、X射线能谱仪（EDS）和X射线光电子能谱仪（XPS）分析试验钢球磨损表面的形貌、元素含量和化学状态，用热重分析仪（TGA）分析了复配聚脲润滑脂的高温稳定性。结果表明，复配添加剂能够显著提高聚脲润滑脂的承载能力和抗磨、减摩性能，其原因归结为润滑脂添加剂在摩擦副表面形成了多种摩擦化学反应膜。

Abstract: Several kinds of grease additives were added to polyurea grease. The sensitivity of different additives to friction and wear of polyurea grease was studied by using MS-10 four-ball friction tester. The wear surface morphology, element content and chemical state of the steel balls were analyzed by scanning electron microscope (SEM), X-ray energy dispersive spectrometer (EDS) and X-ray photoelectron spectroscopy (XPS), and the high temperature stability of the polyurea compound grease was analyzed by thermogravimetric analyzer (TGA). The results showed that the load-carrying capacity, anti-wear and friction reduction performance of polyurea grease could be improved obviously by the compound additives.

Key words: polyurea grease, additives, friction reduction, anti-wear, bearing capacity
