Abstract

The phasing of the friction process provides for the formation of the intersurface phase of the rubbing surfaces of the friction pair, the “third body”. In essence, the third body is a hinge of internal friction of a developed stage of joint plastic deformation of surfaces. Being a consequence of the self-organization of surface adaptation processes in the presence of environmental chemistry, the third body can have a wide range of tribological properties. These properties, in turn, are a consequence of the formation of a wide range of optimal (compatible) structures of the third body, which determines the controllability of friction. The relationship of structure and properties as the basic principle of tribomaterial science provokes the question of what are the limits of this relationship? For example, what are the minimum properties of friction and how are they reflected in the essence of the structural structure and behavior of the friction contact? The equation of a quasi-ideal solid third body under friction is obtained, which proves the existence of an elementary structural element of a solid body under friction (deformation), a mechanical (nano) quantum. A mechanical quantum, as an ideal (theoretical) crystal of atomically rough and spherical shape, is an oscillator of dynamic dissipative friction structures. The potential energy accumulated initially during the evolution of contact is further dissipated in the area of compatibility into these formed mechanical quanta of the third body (elementary tribosystem) in the form of surface energy, creating prerequisites for their elastic reversals with an abnormally low coefficient of friction between them. The efficiency of the third body is proportional to the spectrum of elastic reversals of structural shapes.

根据机械(纳米)量子模型论第三体的结构超塑性
摘要--摩擦过程的分阶段规定了摩擦副的摩擦表面的表面间阶段,即 "第三体 "的形成。实质上,第三体是表面联合塑性变形发展阶段的内摩擦铰链。作为表面适应过程在环境化学作用下自组织的结果,第三体可以具有多种摩擦学特性。这些特性反过来又是第三体形成各种最佳(兼容)结构的结果,这决定了摩擦的可控性。结构与性能的关系是摩擦材料学的基本原理,这引发了一个问题:这种关系的极限是什么?例如,摩擦的最小特性是什么,它们如何反映在摩擦接触的结构结构和行为的本质中?我们得到了摩擦下准理想固体第三体的方程,证明了摩擦(变形)下固体第三体的基本结构元素--机械(纳米)量子的存在。机械量子作为原子粗糙球形的理想(理论)晶体,是动态耗散摩擦结构的振荡器。最初在接触演变过程中积累的势能在相容区域以表面能的形式进一步耗散到第三体(基本摩擦系统)的这些已形成的机械量子中,为它们之间的弹性反转和异常低的摩擦系数创造了先决条件。第三体的效率与结构形状的弹性反转谱成正比。
