It is shown that the wear kinetics of steels with diffusion coatings under the conditions of rolling friction strongly depends on the physicomechanical properties and phase compositions of the coatings, hardness of the base, and the modes of thermal and thermochemical treatments. The dependence of the degree of wear on the number of loading cycles is always parabolic. The contact fatigue strength in rolling is strongly affected by the ratio of slip and deformation components of wear. The deformation component is predominant for low hardnesses of the surface and the base and results in the minimum contact fatigue strength. At the same time, the slip component prevails for high hardnesses of the base and corresponds to the highest contact fatigue strength under the conditions of rolling friction.

具有扩散涂层的钢在滚动摩擦中的磨损动力学

结果表明，在滚动摩擦条件下，具有扩散涂层的钢的磨损动力学很大程度上取决于涂层的物理机械性能和相组成、基体硬度以及热处理和热化学处理方式。磨损程度与加载循环次数的相关性始终是抛物线。滚动接触疲劳强度受磨损的滑移和变形分量之比的影响很大。变形分量主要用于表面和基部的低硬度，并导致最小的接触疲劳强度。同时，滑移分量主要用于基体的高硬度，对应滚动摩擦条件下的最高接触疲劳强度。
