“…In foundry production, the "classic" (basic) technology for obtaining a liquid melt which is poured into the mold is metal smelting in a steelmaking unit (for example, in an arc steelmaking or induction furnaces) [1,2]. Overheating of the obtained metal is not allowed primarily due to increased wear of the furnace lining and increased soot of the alloying elements.…”

The technology of forming a thermite alloy layer on the basis of Fe-Cr-C system on a metal basis by self-propagating high-temperature synthesis is offered, which allows to obtain cast functionallayers withphysico-mechanical and exploitativeproperties. The optimal technological parameters of the forming a wear-resistant layer of thermite alloy process are determined: the amount of metal filler with the maximum yield of suitable alloy, the heating temperature of the thermite charge and the mold to obtain additional heat, the temperature ranges of the melt to melt the metal base with further formation of the functional layer. Metallographic studies of the obtained wear-resistant layer of thermite allo[y showed that the zone of formation of the functional layer is characterized by the stability of the macrostructure and the positive effect of non-metallic inclusions in the form of Al2O3, which influences the formation of chromium carbides in the obtained alloy by creating the effect of inoculative modification of thermite alloy.
