Abstract An attempt was made to determine the influence of the nature of the lubricating medium on the qualitative composition of wear products during long-term frictional interaction of a brass-steel friction pair in model media. Copper nanoparticles deposited on the steel surface in the form of a tribo-film are formed in the lubricant composition. Using quantum chemical calculations, it was shown that carboxylic acids form complexes with copper ions and clusters. The concentration of iron ions decreases during the transition from formic to caproic acid in the homologous series of monobasic carboxylic acids. It is shown that particles of wear products agglomerate in a lubricating medium with an increase in the time of frictional interaction of friction pairs.

黄铜-钢对摩擦过程中的磨损产物和摩擦化学反应

摘要 试图确定润滑介质的性质对模型介质中黄铜-钢摩擦副长期摩擦相互作用期间磨损产物定性成分的影响。在润滑剂组合物中形成以摩擦膜形式沉积在钢表面上的铜纳米颗粒。使用量子化学计算，表明羧酸与铜离子和簇形成络合物。在一元羧酸的同源系列中，在从甲酸到己酸的转变过程中，铁离子的浓度降低。结果表明，随着摩擦副的摩擦相互作用时间的增加，磨损产物颗粒在润滑介质中聚集。
