Abstract—

Within the framework of physicochemical mechanics (the Rehbinder effect), the problems of the plasticizing and strengthening effect of the lubricating medium on the near-surface layers of metal tribomaterials are analyzed. The influence of modeling (petroleum jelly oil, glycerin, mineral oils, glycerin-based hydraulic fluids) and industrial (Buksol, Puma, and M-14V2) lubricant media that contain surfactants, is investigated on the main tribological (coefficient of friction, wear intensity), strength (yield strength, microhardness) and microstructural (broadening of X-ray lines, dislocation density and crystal lattice parameter) characteristics, as well as on the processes of diffusion redistribution of alloying elements in surface layers of tribomaterials, such as copper, brass, and bronze, when they are rubbed together with steel. The analysis of the conditions of formation and stable functioning of the regime of “non-wear” friction in these tribomaterials is carried out. It is shown that among industrial copper alloys, brass of the L90 type, aluminum bronzes BrA5 and BrA7, and tin bronzes BrSnP4-0.25 and BrSnP6.5-0.15 have the greatest wear resistance in surface-active lubricants. Examples of the implementation of the selective transfer mode in tribo-pairs used in railway and motor transport are given.

活性润滑介质中重载摩擦副工作时减摩材料的物理化学摩擦力学

摘要-

在物理化学力学（Rehbinder效应）的框架内，分析了润滑介质对金属摩擦材料近表层的塑化和强化作用问题。研究了含有表面活性剂的建模（凡士林油、甘油、矿物油、甘油基液压油）和工业（Buksol、Puma 和 M-14V2）润滑介质对主要摩擦学（摩擦系数、磨损）的影响。强度）、强度（屈服强度、显微硬度）和微观结构（X射线线展宽、位错密度和晶格参数）特性，以及摩擦材料（例如铜）表面层合金元素扩散再分布的过程、黄铜和青铜，当它们与钢一起摩擦时。对这些摩擦材料中“非磨损”摩擦状态的形成条件和稳定功能进行了分析。结果表明，在工业铜合金中，表面活性润滑剂中L90型黄铜、铝青铜BrA5和BrA7以及锡青铜BrSnP4-0.25和BrSnP6.5-0.15的耐磨性最好。给出了在铁路和汽车运输中使用的摩擦副中实施选择性传递模式的示例。
