“…Improving the performance of parts and tools subject to intense wear is an urgent task of mechanical engineering [1][2][3][4][5]. Well-known methods for modifying the surface of parts and tools include PVD [6][7][8][9][10][11][12], CVD [13][14][15], and directed energy deposition (DED) [16]. In addition, known methods include (1) self-lubricating coatings obtained by laser additive manufacturing technology for friction reduction [17]; (2) textured coatings operating without lubrication and obtained by laser technologies [18]; (3) composite ceramic coatings obtained by the method of electric arc surfacing [19]; and (4) plasma electrolytic oxidation, also called micro-arc oxidation [20].…”

In this work, the features of the phase composition, structures, and properties of coatings obtained on a high-speed steel substrate (steel R6M5) were studied. The coatings were prepared using the ESA method (electro-spark alloying). Electrode materials prepared through self-propagating high-temperature synthesis (SHS) based on (Ti-B-Fe)xAlN with the addition of nanosized AlN particles in the amount of x = 0.5, 10, 15 wt % were used as electrodes. The structure, phase composition, and physical and mechanical properties of the SHS electrode materials are reported. It was found that the coatings inherited the structure of the SHS electrode material and formed two characteristic zones for x = 0 and three zones for x = 5, 10, 15. The surface hardness of the substrate made of the high-speed steel R6M5 with the developed coatings was found to increase up to five times compared to the uncoated substrate. It was found that the wear resistance of the samples with the coating was four to six times higher than that of uncoated samples.
