64-66

There's carried out the comparison of fretting resistance of electrolytic coats with rheological constants values, corresponding to equal homological temperature. As a friction resistance criterion the quantity of fretting cycles, including unit depth wear served. Investigation results show, that there's apparent the close to linear dependence of fretting-resistance on rheological constant value: the more material prones to microcreep, the higher its fretting-wear resistance is. It's investigated dependence of local adhesion wear on steel 40X limit of elasticity in various structure states, reached after thermal treatment. There's shown the influence of hardened steel temper temperature and friction load conditions on structure-dislocation and magnetomechanical mechanisms, and also on internal friction.
