Research methods - the structure and properties of deposited coatings were studied by electron microscopy, micro-X-ray spectral, metallographic, X-ray phase analysis; tests for hardness and abrasion resistance, in particular under conditions of impact and abrasive wear. Ferroalloys of (Mn, Nb, Mo, V, Cr), refractory carbide powders (titanium, niobium, vanadium, molybdenum and tungsten), as well as reaction mixtures of metals (titanium and molybdenum) with carbon were used as the charge for powder electrodes. soot) and boron carbide. The obtained results – as a result of theoretical and experimental studies, compositions of powder electrode materials were developed, which provide the formation of metal-ceramic composite structure of the deposited layer. Electrode materials from leading world manufacturers, such as Lastek (Belgium), ESAB (Great Britain) and others, were selected for comparative analysis of wear resistance in tribotechnical tests to determine abrasive wear resistance. According to the results of comparative analysis, it was found that among the studied coatings the highest indicators of wear resistance (1.2 - 1.5 times higher than serial) are characterized by experimental coatings. Electrode materials in the form of tapes for electric arc surfacing have been successfully tested at enterprises specializing in woodworking, renewable energy, brick industry and others. Areas of application - oil and gas, renewable energy (production of fuel briquettes), mining, metallurgy (grinding, mining and transport equipment); defensive (steel armor plates with impact-resistant coatings).
