Abstract
The reaction formation of composite materials and coatings based on titanium boride, silicon dioxide, and silicon carbide upon heat treatment of mixtures composed of initial components in air has been investigated. It is shown that the glass melt formed in the course of the chemical reaction encapsulates titanium boride and silicon carbide particles, thus imparting the high-temperature strength to the composite material. The influence of the composition, temperature, and heating conditions on the kinetics of oxidation of samples in the form of cast pieces and graphite with coatings during their heat treatment at temperatures of 1000–1300°C is studied using thermogravimetric, differential thermal, and X-ray powder diffraction analyses. The electrical resistivity of the synthesized samples is determined and its dependence on temperature is established. The compositions of coatings that ensure the effective protection of graphite from oxidation in air at high temperatures are proposed from analyzing the results of the performed investigation.
