During the joint electrospark dispersion of titanium with VyMoz alloys in hexane, complex carbides (TixVyMoz)C with a cubic lattice are formed. Assuming that complex carbides (TixVyMoz)C as quasi-binary systems, where complex carbide (VyMoz)C with a cubic structure is dissolved in cubic titanium monocarbide, the composition of complex carbides (Ti0,75V0,05Mo0,20)C and (Ti0,65V0,31Mo0,04)C, formed by electrospark dispersion of Ti-V0,2Mo0,8 and Ti-V0,2Mo0,8 pairs. Using the method of differential thermal analysis, it was shown that the thermal stability against oxidation of complex carbides (TixVyMoz)C, synthesized by joint electrospark dispersion of titanium and the VyMoz alloy, depends on the ratio of metals. Thermal stability against oxidation increases with an increase in the content of titanium and molybdenum in the composition of complex carbides; their resistance to oxidation increases. It has been established that intensive oxidation of complex carbide (Ti0,75V0,05Mo0,20)C occurs at 595oC, and complex carbide (Ti0,65V0,31Mo0,04)C oxidizes at the maximum rate at 520oC.
