摘要 在水介质中原位制备纳米硅酸镁和纳米硅酸锌,在四球摩擦磨损试验机上评价水介质中两种纳米硅酸盐及其与油酸三乙醇胺(OATEA)复合后的抗磨减摩性能,采用扫描电镜(SEM)和X射线光电子能谱仪(XPS)分析磨斑表面形貌和主要元素的化学特征。结果表明:水介质中纳米硅酸镁和纳米硅酸锌的抗磨减摩效果不佳、性能相近,但与OATEA复合后抗磨减摩性能显著提高。原因一方面是具有表面活性的OATEA在摩擦表面形成具有良好润滑作用的吸附或反应润滑膜,另一方面是摩擦化学反应生成的SiO2起到"微滚动轴承"的作用,并与表面形成的Fe3O4、Fe2O3以及OATEA边界膜共同减小摩擦磨损。 Nanometric magnesium silicate and zinc silicate were prepared in water by method of chemical deposition. The antiwear and friction reducing abilities of the nano-silicates, as well as their composites with oleic acid triethanolamine (OATEA), were evaluated on a four ball friction tester. The topographies and chemical features of the worn surfaces were analyzed by scanning electron microscope (SEM) and X-ray photoelectron spectroscope (XPS). The results show that nanosilicates alone provide poor antiwcar and friction reducing abilities in water, but exhibit excellent antiwear and friction reducing capacities when formulated with OATEA. The synergistic effect in reducing friction and wear between nano-silieates and OATEA may be attributed on one hand to the formation of a boundary lubrication film on the friction surfaces by OATEA, and on the other hand to the production of silicon oxide, which acts as "micro-milers" between friction pairs and cooperates with iron oxides and OATEA surfacial film to further reduce friction and wear.
