采用干混研磨法制备β－环糊精（β?CD）与亚磷酸二正丁酯（ T304）的包合物。采用四球法研究不同含量的包合物在聚乙二醇－600（ PEG?600）溶液中的摩擦学性能。摩擦磨损实验结果表明，在不同载荷下，包合物的抗磨减摩性能都优于β?CD，这是因为在摩擦过程中，包合物分解成各种分子片段，释放T304分子；包合物质量分数为0?9％时，摩擦系统的摩擦因数最小。磨损表面的X射线光电子能谱（ XPS）分析表明，被释放的T304形成的亚磷酸盐和亚磷酸酯膜起主要作用，β?CD的分解片段形成的羟基吸附膜和碳沉积膜在亚磷酸盐和亚磷酸酯膜上具有更好的抗磨作用；不同润滑膜的相互作用最终形成了混合边界润滑膜。

The inclusion complex of β?cyclodextrin(β?CD)and dibutyl phosphite(T304)was prepared by trituration. The tribological properties of the complex with different concentrations were investigated by a four?ball tester in the solution of polyethylene glycol?600(PEG?600).The tribological test results show that the complex exhibits better friction reducing and anti?wear properties thanβ?CD under different loads,that is because that the complex is decomposed into various mo?lecular fragments and the T304 molecules are released under the friction condition.The tribo?system shows the least friction coefficient when the concentration of the complex is 0?9%. The XPS analytical results on the worn surfaces reveal that phosphide films formed by the released T304 play a major role and the iron alkoxide and carbon deposition films formed by the β?CD fragments have better friction reducing effect on the phosphide film surface.The interactions of different films re?sult in the formation of a mixed boundary lubrication film.
