Experimental diagnostics of the composition and structure of titanium diboride-containing materials obtained by self-propagating high-temperature synthesis from reaction mixtures of the titanium/ferrotitanium-ferroboron system is performed. Results of testing of specimens for compressive strength and wear resistance under dry friction against a fast abrasive are presented. The effect of 20 and 50 wt.% additions of copper or nickel to the initial reagents on the properties, structure and phase composition of the materials obtained is analyzed. It is shown that the materials without additions of copper and nickel have the highest wear resistance, while those containing Co and Ni have an elevated strength.
