Investigation of combustion synthesis products in titanium, carbon and aluminum powder mixtures
Products of the combustion in titanium, carbon (black carbon) and aluminum powder mixtures have been investigated by X-ray diffraction, scanning electron microscopy and local X-ray spectroscopy methods. Titanium carbide and ternary compounds are synthesized in wave mode combustion reaction. An impact of the carbon to aluminum ratio in the reaction mixtures on combustion temperature, phase composition and microstructure of the synthesis products is determined. The titanium carbide was found to be the basic phase in the synthesis products. The size of the carbide particles in the composite structure decreases monotonously as the carbon to aluminum ratio reduces. This is due to the combustion temperature drop when carbon to aluminum ratio reduction. On the basis of results of the structure researches the prospects of using of the composites for the coatings deposition and for production of the solid materials by hot compacting or spark plasma sintering.
