“…As the result of the combination of technological procedures changing the surface, microhardness of the surface layers is increased. Microstructural researches have demonstrated that a modified layer is observed, with granular structure, clearly different from the remaining mass [4]. The enhancement of hardness and strength properties is conditioned by the reduction of grain size.…”

“…The details of the technological process of mineral layers' creation, as well as structural changes on the surface and subsurface layers of metal samples (chromium steels, titanium alloys) are described in the work [4]. As the result of the combination of technological procedures changing the surface, microhardness of the surface layers is increased.…”

“…Besides, the pictures in figure 2 show microcavities randomly scattered over the working surface of the sample. It is due to these created microcavities that the oil is detained when lubrication is suspended, which may be listed among the advantages of the technology [4] because performance capabilities and equipment safety are enhanced during start-and-stop operations, e.g. spindle bearings in case of insufficient lubrication.…”

“…Figures 2 and 3 clearly demonstrate that after 10 million cycles of slip-rolling abrasion test the surfaces with mineral coating, exposed to friction, became smoother. It is possible that the technology of creating a thin modified layer on a metal surface, leading to its local strengthening and enhanced hardness [4], preconditioned good slip-rolling friction resistance of the samples made of 12Х13 and ШХ15 (Russian equivalent of 102Cr6 German steel) steels, which was probably defined by general residual compression stresses.…”

IntroductionThe core indicators of the quality of machine's parts, assemblies and mechanisms are reliability and lifespan, which are greatly defined by the properties of the surface layers of parts and junctions: wear resistance, corrosion resistance, friction rate, contact rigidity, seating stability, connection tightness. The reason for a short lifespan of parts and other structural components may be significantly associated with tear-and-wear and corrosive deterioration of their surface layers. To eliminate or slow down the processes taking place on the border between metal and environment, which have a negative effect on the operability of materials, various types of surface treatment are used. Besides multiple methods involving coatings, films and protective layers, there is a rapidly developing modern technology of changing physical and chemical properties of surface layers of metal parts by means of modification. In particular, industrial application of natural minerals for hardening surface layers of structural materials is finding its niche, due to the effects, combination of which leads to enhanced wear resistance, anti-friction, anti-corrosion and other specific properties of a friction pair.

The resistance of mineral coatings created on the surface of specimens of 20X13 steel (Russian analogue of steel 20Cr13 (EU)) modified with ultradispersed mineral particles to abrasive wear during friction against fixed particles was determined, and the wear parameters of layers modified with mineral particles were compared with the parameters of surface layers created by laser cladding of alloys of different compositions. The studies were carried out on an experimental setup for testing abrasive wear under a static load of 60 N and 160 N and determined the weight wear, the average wear rate and the average wear rate of the surface layer of three samples with different mineral coatings. According to the results of measurements at a pressure on the wear surface of 0.5 MPa, a sample was determined with an indicator of weight wear comparable to a coating made of cobalt alloy, created by the method of laser cladding and about four times inferior in this indicator, to a coating of a nickel alloy, created by the method of laser cladding and tool steel. The practical use of various methods of protecting parts from abrasive wear is determined, along with the physical and technical characteristics of the layers, by the economic feasibility in specific operating conditions.
