The effect of antifriction additives based on dialkyldithiophosphoric acid and molybdenum-containing friction modifiers (A-22, A-23, A-24, DF-11, PAF-4, TEF-3, ADTF ) on the tribological characteristics of polyurea lubricating greases based on petroleum and synthetic oils is discussed. The dependence of the tribological characteristics of polyurea plastic greases on the nature, the concentration of the additive (1-3 wt. %), and the dispersion medium was studied. The antiwear and extreme pressure characteristics were determined by three well-known standard methods: ChMT-1 four ball wear tester; Brugger tribometer; KT-2 four ball tester.

通过使用功能性添加剂改善聚脲润滑剂的摩擦学性能

基于二烷基二硫代磷酸和含钼的摩擦改进剂（A-22，A-23，A-24，DF-11，PAF-4，TEF-3，ADTF）的减摩添加剂对聚脲润滑脂的摩擦学特性的影响讨论了基于石油和合成油的产品。研究了聚脲塑料润滑脂的摩擦学特性对性质，添加剂浓度（1-3 wt。％）和分散介质的依赖性。耐磨性和极压特性是通过三种众所周知的标准方法确定的：ChMT-1四球磨损测试仪；布鲁格摩擦计; KT-2四球测试仪。
