摘要:

SiOC陶瓷因耐高温、低密度、低热导及低成本等优异特性,在航空航天防隔热一体化材料领域具有重要应用前景。然而,SiOC陶瓷在高温氧化环境中易发生结构破坏和性能退化,因此,有必要深入理解SiOC陶瓷的氧化行为,优化其抗氧化性能,从而使其满足更高的使用要求。本文系统综述了SiOC陶瓷氧化行为,总结了元素掺杂改性、复合材料设计及表面涂层三种抗氧化策略的研究现状,揭示其在高温环境下微观结构演变与宏观性能关系,并对后续复合材料的抗氧化研究和应用提出了发展建议。

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
