Long-time ablation-resistant zirconium carbonitride ultra-high-temperature ceramic-based composite material as well as preparation method and application thereof
The invention discloses a long-time ablation-resistant zirconium carbonitride ultrahigh-temperature ceramic-based composite material as well as a preparation method and application thereof, and belongs to the technical field of preparation of composite materials for aerospace. According to the invention, the short carbon fiber toughened ZrCxNy ceramic-based composite material with the density of greater than or equal to 92% is prepared by a wet ball milling, ultrasonic heating and stirring and spark plasma sintering process for the first time. The nitrogen-containing carbide ultrahigh-temperature ceramic-based composite material designed and prepared by the invention is suitable for ultrahigh-temperature ablation-resistant protection at 2500 DEG C or above. Verification shows that after long-time (200s) ablation, the ceramic still keeps a state close to zero ablation rate and a continuous and stable anti-oxidation protection structure.
本发明公开了一种长时耐烧蚀碳氮化锆超高温陶瓷基复合材料及其制备方法、应用，航空航天用复合材料制备技术领域。本发明首次提出通过湿法球磨+超声加热搅拌+放电等离子烧结工艺来制备致密度为≥92％的短切碳纤维增韧ZrCxNy陶瓷基复合材料。本发明所设计和制备的含氮碳化物超高温陶瓷基复合材料使得其适用于2500℃及以上超高温抗烧蚀防护。通过验证发现经长时间(200s)烧蚀后陶瓷仍保持接近零烧蚀率的状态和连续稳定的抗氧化防护结构。
