The paper presents the results of the X-ray diffraction analysis, scanning electron microscopy, and electron probe micro-analysis of the products synthesized from the titanium, carbon (soot), and aluminum powder compositions in the wave combustion mode. It is found that the carbon/aluminum ratio in the reactive powder compositions has an effect on the combustion temperature, phase composition, and structure of the synthesis products. The major phase in the synthesis products is titanium carbide with the particle size monotonically decreasing in the composite structure with decreasing carbon/aluminum ratio in the reactive powder compositions resulting from the reduction in the combustion temperature. Based on the structural investigations of the synthesized composites, their practical application as feedstocks is discussed in relation to the coating deposition and cladding, and as bulk materials consolidated via hot isostatic pressing or spark plasma sintering.
