AB A mathematical model of the thermal processes of self-propagating high-temperature synthesis in the formation of wear-resistant coatings by pulse plasma processing of a composite plaster of a charge containing SHS reagents has been developed. The boundary-value problem is solved by a finite volume method in a two-dimensional formulation using iterative processes. It is shown that the character of SHS depends substantially on the plasma jet power, processing distance, warming of the substrate, and on the internal energy of agglomerates (microcomposites) after mechanical activation of the initial charge. Optimal modes of forming Ni/NiCr + TiC composite coatings have been determined with the aid of computational experiments.
