| Summary: | Abstract 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 -SiC-ZrO 2 system to high-temperature corrosion is achieved owing to formation of protective oxide layer with variable composition. A key area for the use of the material in the Arctic is the organization of heat-shielding structures in the oil and gas industry. |
