摘要
由于在极端环境中具有优异的物理化学性能,超高温陶瓷成为未来高超声速飞行和可重复使用运载飞船领域最具前途的候选材料之一。本文对硼化锆基超高温陶瓷材料粉体合成、烧结致密化和高温热机械性能(主要为抗氧化和抗烧蚀性能)研究方面作了综合评述,对材料研究和应用方面存在的问题作了初步总结,期望能够为推动超高温陶瓷材料的实际应用起到一定的指导意义。
Ultra-high temperature ceramics（UHTC） have become one of the potential strategic materials in the fields of future hypersonic flights and reusable launch vehicles due to their excellent physical and chemical properties in the extreme environments.Powder synthesis process,sintering,high temperature thermo-mechanical properties,especially oxidation and ablation resistances were systemically reviewed.Also,the problems in the material research and applications were preliminarily summarized.It is expected this will provides some guidance for propelling the practical applications of the UHTCs materials.
