摘 要:C_(f)/C复合材料具有低密度、高热导率、优秀的抗侵蚀性能和良好的抗热震性能等优点,在高超声速飞行器、飞机刹车盘和火箭喷管等高端结构材料领域具有广阔的应用前景。然而,由于C_(f)/C复合材料的高氧化敏感性,其易产生严重的化学烧蚀和服役性能退化等问题。在C_(f)/C复合材料表面制备ZrB_(2)-SiC基超高温陶瓷基涂层是上述问题的最有效解决方案。基于此,本文综述了ZrB_(2)-SiC基超高温陶瓷涂层的组成/结构设计和抗氧化性能及强化机理的研究现状,系统地分析了ZrB_(2)-SiC基陶瓷涂层常用制备方法的原理和优缺点,并且对本领域研究的未来发展方向进行了展望。Owing to their outstanding properties including low density,high thermal conductivity,good ablation and thermal-shock resistances,C_(f)/C composites have great potentials in various high-end structural application fields such as hypersonic aircraft,aircraft braking systems and rocket nozzles.However,the high oxidation sensitivity of C_(f)/C composites generally causes some severe problems including serious chemical ablation and significant degradation of service performances.To address these problems,the preparation of ZrB_(2)-SiC-based ultra-high temperature ceramics(UHTCs)coatings on the surface of C_(f)/C composites is the most effective solution so far.Consequently,this paper reviewed the recent progress in the topics of compositional/microstructural modifications of ZrB_(2)-SiC-based coatings,their oxidation resistances and enhancement mechanisms.Moreover,the principles as well as advantages/disadvantages of popular preparation methods of ZrB_(2)-SiC-based ceramic coatings were summarized.Based on this,the prospects of the promising directions of research and the technique development of this field were forecasted.
