| 摘 要： | 采用化学法合成了PS-TiO2复合纳米微球，并对其进行了TEM、 FTIR、 TGA及DSC等分析表征。将这种微球用作润滑油添加剂,在四球试验机上研究了它的减摩抗磨性能，同时又对磨斑表面进行了X射线光电子能谱分析(XPS).研究表明：这种添加剂有良好的抗磨性能，并能在摩擦表面形成由TiO2、 Fe2O3以及有机碎片所组成的边界润滑膜。

| Abstract: | Polystrene（PS）-TiO2 nano-spheres were chemically synthesized. The structure characterization of theprepared PS-TiO2 nano-spheres was investigated by means of transmission electron microscopy（TEM）and Fouriertransform infrared spectroscopy（FTIR）. The thermal stability of PS-TiO2 nano-spheres was identified using athermal analyzer（DSC & TGA）. The tribological behaviors of PS-TiO2 nano-spheres as additives in paraffin oilwere evaluated on a four-ball machine. The worn surfaces were analyzed with X-ray photoelectron spectroscopy（XPS）also. Experimental results indicate that the PS-TiO2 nano-spheres，under a certain condition，have agood anti-wear performance and improve striking failure load. This is attributed to the formation of a chemical reactionboundary film consisting of TiO2，Fe2O3 and organic fragments. |
