“…An increase in surface hardness led to an increase in its wear resistance (Table 4). It has been established that the wear resistance index of the samples with coatings based on (Ti-B-Fe) x AlN, calculated according to the method in [40] was four to six times higher than that of an uncoated sample (Table 4). Consequently, the developed (Ti-B-Fe) x AlN coatings improved the tribological properties of the treated metal substrate and increased its wear resistance.…”

“…Free SHS compression [36][37][38] and SHS extrusion are promising methods for obtaining compact electrode materials. One of the promising methods for obtaining ceramic and cermet electrode materials used in electro-spark alloying is the SHS extrusion method [39][40][41][42]. The method is based on a combination of combustion processes in the mode of selfpropagating high-temperature synthesis [43][44][45] and subsequent high-temperature shear deformation.…”

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.
