It has been found that empirical analysis provides a possibility to select the optimum concentration of the repair and restoring composition (RVS), addition of which to the transmission oil provides an increase in wear resistance of 42Cr4 steel under rolling and slip conditions. The structural adaptability of finely dispersed components of the friction geo-modifier RVS, boundary lubricating films and surface layers of metal under friction and under dynamic loading conditions contribute to reducing the wear of contact surfaces. It has been established that the addition of 1.5 % RVS to the lubricant provides a 17 % reduction in the wear of rolling friction pairs, provides hardening of the surface layers of the metal by 1.36 times, compared with the initial surface. The micro-hardness of the surface layers of the metal and its gradient depth distribution, the microgeometry of the surface layer formed during friction, and the formation of boundary lubricating layers on the friction-activated contact surfaces are key indicators that increase the wear resistance in friction pairs.

Annotation In this scientific work, we proposed a scheme for the transformation of a physical model of applying the HFI plasma coating to a mathematical one in a mathematical way by stepwise solving the problems of the structural model stages. The equations of conservation of energy of the electron gas, Maxwell, continuity and momentum will be used. It is planned to develop a mathematical model for sputtering dielectric and metallic materials. In this case, boundary conditions will be introduced for the discharge power, flow rate and gas types, pressure and design parameters of the plasma torch.

The aim of this work is to investigate the tribological behaviour of a continuous hot dip galvanizedsteel. This paper presents a fundamental study of the characteristics of zinc coating in terms ofmorphology, surface roughness and tribological behavior according to process parameters typical ofindustrial processes continuous galvanization. The morphology of the zinc coating was observed byscanning electron microscope (SEM), optical microscopy, and the mechanical properties of thecoating layers were determined by nanoindentation. The tribological tests were carried out on arotating ball-disk tribometer under loads of 1, 2, 3Nwith a sliding distance of 15, 30 and 50 m. Theresults showed a marked increase of the coefficient of friction with increasing applied load. Under thesame conditions, wear slightly increased due to the hardness of intermetallic phases. The resultspresented show that heating promotes the diffusion of iron in the zinc coating giving shape to a binaryalloy Fe-Zn whose characteristics depend on the parameters; moreover, it is proved that thetribological characteristics of the surface of the metal blank in terms of coefficient of friction dependon the temperature of the contact pressure.
