摘要:

碳化锆(ZrC)陶瓷复合材料具有熔点高、密度低、耐烧蚀的优点, 在超硬、航天防热、新能源等领域应用前景广阔。本文概述了ZrC金属陶瓷和复相陶瓷、纤维增强ZrC复合材料的制备方法。着重介绍了粉末烧结、先驱体转化、反应浸渗等工艺的应用, 并讨论了不同制备工艺下复合材料显微组织的特点。在总结两类材料力学性能和烧蚀性能的基础上, 分析了各自的影响因素, 并指出ZrC金属陶瓷和复相陶瓷韧性低, 纤维增强ZrC复合材料烧蚀层易剥落的问题。最后总结展望了ZrC陶瓷复合材料相关研究的发展趋势。

Abstract:

ZrC ceramic composites have been proposed for a variety of applications in super-hard, thermal protection and new energy fields due to their excellent properties, such as high melting point, low density and good ablation resistance. The preparation techniques for ZrC cements, composite ceramics and fiber reinforced ZrC composites are reviewed, including powder sintering, precursor infiltration and pyrolysis and reactive melt infiltration. The effects of processing on microstructure of ZrC composite are discussed. Mechanical properties and ablation properties of ZrC ceramic composites are summarized. The problems, low toughness and spalling of ablation layer, for ZrC cements, composite ceramics and fiber reinforced ZrC composites are proposed, respectively. Finally, the trend of researches on ZrC ceramic composites is also prospected.

Key words: ZrC ceramic composites, preparation, microstructure, performance, review
