The paper presents the research results on produsing by the method of liquid-phase self-propagating high-temperature synthesis (SHS) the composite metal-matrix alloys intended for the obtaining of wear-resistant coatings by electric spark deposition (ESD). Oxides NiO, Cr2O3 and mineral concentrate ZrO2 were used as a melting charge. Alloys based on the Ni-Al system with aluminides of complex composition containing Cr and Zr were obtained by means of the alumothermic SHS reaction. Wear-resistant coatings were formed on steel 45 by the ESD method by means of the newly obtained alloys,. The maximum wear resistance of the coatings was obtained using the alloys containing Cr (wt% 18) and Zr (wt% 1.9).
