Abstract

Electrospark alloying (ESA) of conducting surfaces of solids is a promising direction for increasing the operational properties of materials at the present time. The formation of coatings of superhard materials on a substrate can significantly increase the hardness, wear resistance, resistance to high temperatures and pressure. This article investigates the chemical composition, structure, physical and mechanical characteristics, morphology of coatings formed on metal substrates. It was found that the technological parameters of the formation of electrospark coatings have a significant effect on the morphology, structure, and physical and mechanical characteristics of the modified materials. The structure of the protective layers depends significantly on the chemical composition of the electrodes. MAX phases are formed in ESA coatings.
