| 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。

| Abstract: | Nanometric magnesium silicate and zinc silicate wer e 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 nano-silicates alone provide poor antiwear and fri... |
