二烷基二硫代磷酸钕作为锂基脂添加剂的极压抗磨作用机理

Antiwear and Extreme Pressure Mechanism of Rare Earth Dialkvldithiophosphate as Lithium Grease Additive

合成了二正十六烷基二硫代磷酸阴离子与稀土离子(Nd^(3+))的中性络合物,考察了具有类似配体结构的稀土和过渡金属(Zn)络合物对锂基脂摩擦学性能的影响,通过X光光电子能谱(xps)对添加剂的作用机理进行了研究。

Coordination compound of di-n-hexadecyldithiophosphate anion with rare earth ion(Nd3+) was prepared.The effect of Zinc and Neodynium dialkyldit-hiophosphate as additives on the tribological characteristics of lithium grease was studied.X-ray photoelectron spectroscopy(XPS)was used to study the worn surface. The antiwear and extreme pressure action mechnisms of additives were proposed.
