Abstract:

Owing to the excellent properties, including high-temperature resistance, low density, low thermal conductivity and cost-effectiveness, SiOC ceramics show significant potential for applications in thermal insulation materials for aerospace. However, SiOC ceramics are prone to structural damage and performance degradation under high-temperature oxidizing conditions, making it essential to gain an in-depth understanding of their oxidation behavior and to optimize their oxidation resistance to meet increasingly demanding service requirements. This paper systematically reviews the oxidation behavior of SiOC ceramics, summarizing recent advances in three antioxidant strategies: element doping modification, composite material design, and surface coating. It reveals the relationship between microstructural evolution and macroscopic properties in high-temperature, and provides developmental recommendations for subsequent research and application of oxidation-resistant composite materials.

Key words: SiOC ceramics, composite, high-temperature oxidation, matrix modification, elemental doping, thermal protective coating
