Using the X-ray phase analysis method, it was established that during the joint electric spark dispersion of titanium with a V-Mo alloy in heptane, the formation of complex carbides (TiхVуМоz)C with a cubic lattice occurs. Assuming that complex carbides (TiхVуМоz)C are quasi-binary systems, where complex carbide (VyMoz)C with a cubic structure is dissolved in cubic titanium monocarbide, the composition of complex carbides (Ti0.65V0.31Mo0.04)C formed during electric spark dispersion of Ti pairs was established –V0.9Mo0.1. Using the method of differential thermal analysis, it was shown that the thermal stability against oxidation of complex carbides (TiхVуМоz)C, synthesized by joint electric spark 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 (Ti0.65V0.31Mo0.04 )C oxidizes at a maximum rate at 520°C.
