摘　　要：从分子设计的观点出发,设计并合成了硼化含氮杂环衍生物,考察了其作为润滑油添加剂的抗磨性能,并通过扫描电子显微镜和X射线光电子能谱仪分析探讨了其在基础油中的抗磨作用机理.结果表明:所合成的硼化杂环衍生物添加剂在摩擦表面生成了由非牺牲性B2O3沉积层、氧化物、酸性氧化产物和聚合物组成的润滑及防护薄膜,从而有效地起到抗磨作用.A heterocyclic compound containing B and N was designed and synthesized. The tribological behavior of the synthetic heterocyclic compound as an additive in 350SN base oil was evaluated on a fourball machine, and the action mechanism of the additive was discussed based on observation of the worn surface morphology with a scanning electron microscope and analysis of the chemical states of some typical elements on the worn steel surface with an Xray photoelectron spectrometer. As the results, a lubricating and protective film composed of B2O3, inorganic oxide, and the oxidized and polymerized product of the additive was formed on the worn steel surface, which contributed to reduce the friction and wear of the steelsteel pair.
