Ultra-high-temperature ceramics based on zirconium diboride and silicon and hafnium carbides are presented as composites with ceramic matrix and oxidation-resistant surface. Relatively low density, high strength at extreme temperatures and operability at oxidative environment with temperature up to 2000°C make these materials useful for aerospace construction and power engineering. HfC-ZrB[2]-SiC-ZrO[2] systems are presented, structural analysis and the results of temperature tests in high-enthalpy gas are provided. It was demonstrated that high resistance of HfC-ZrB[2]-SiCZrO[2] system to high-temperature corrosion is achieved owing to formation of protective oxide layer with variable composition.
