摘　　要：以碳纤维增强碳基(C/C)复合材料为例的航空航天飞行器热结构部件服役条件恶劣,往往需要在其表面制备氧化防护陶瓷涂层,以抵御热-力-氧耦合环境的侵蚀。然而,自身脆性导致陶瓷涂层极易在外力作用下出现损伤,严重威胁热结构部件的服役安全性。针对氧化防护陶瓷涂层的损伤修复需求,基于涂层的损伤尺度,分别介绍了面向微观损伤的自修复技术与面向宏观损伤的再制造技术,针对两类技术的具体实施方式、研究现状、修复效果、优缺点及各自的适用场景进行了阐述,最后对氧化防护陶瓷涂层自修复与再制造的未来发展方向进行了展望。The thermal structural components of aerospace vehicles using carbon fiber reinforced carbon matrix(C/C)composites as raw materials,are facing harsh service conditions and require oxidation resistant ceramic coatings on their surfaces to resist the erosion in thermo-mechanical-oxygenic coupling environments.However,the brittleness of ceramic coatings make them highly susceptible to damage under external forces,posing a serious threat to the service safety of thermal structural components.Driven by the repair needs of oxidation resistant ceramic coatings and based on the damage size of coatings,the self-healing technology for micro damage and the remanufacturing technology for macro damage are introduced.The implementation methods,research status,repair effects,advantages&disadvantages and application scenarios of the two technologies are elaborated.Finally,the future development directions of the self-healing and remanufacturing of oxidation resistant ceramic coatings are discussed.
