原始语种摘要: As determined, an increase in the fatigue crack resistance of machine parts at frictional hardening of their working surfaces essentially depends on the choice of the technological environment. A complex local study of the influence of different working media on the phase and chemical compositions, microstructure, and stress state of friction-hardened steel 45 is carried out. As shown, a saturation of friction-hardened metal with active chemical elements from lubricoolants influences on the fatigue crack resistance of articles. These chemical elements are predominantly located in the near-boundary regions of grains. They do not form any chemical compounds with the atoms of the parent metal and significantly change both the electronic structure and the nature of chemical bonds between the...
