摘　　要：利用四球试验机考察了所合成的苯并噻唑衍生物添加剂在基础油中的摩擦学性能,并用X射线光电子能谱仪和扫描电子微探针观察分析了磨斑表面的元素化学状态。研究结果表明:苯并噻唑衍生物可以显著改善基础油的抗磨性能和承载能力;添加剂在摩擦过程中发生了摩擦化学反应,生成了含有机硫化物、硫酸亚铁等的边界润滑膜,从而改善了基础油的抗磨性能。The tribological performance of 2-（N-alkylcarbamoylmethyl） thiobenzothiazole as an additive in liquid paraffin was evaluated by four-ball machine. The tribochemical reaction of the compound with the metal surface was investigated by X-ray photoelectron spectroscopy and scanning auger microprobe techniques. The compound possesses higher load capacity and better lubricating characteristics. The tribochemical reaction is observed between the compound and surface of sliding pairs. A surface film containing inorganic/organic sulfur compounds is observed.
