中文摘要：
金属硅化物因具有高熔点、高辐射及高温抗氧化性而成为高超声速飞行器陶瓷防隔热瓦表面涂层最具潜力的材料.综述了难熔金属硅化物作为大面积区域采用的陶瓷隔热瓦表面高发射率涂层材料和高温区采用的陶瓷防热瓦表面抗氧化涂层材料的研究现状,介绍了涂层制备方法的优缺点,提出了陶瓷复合材料表面涂层当前研究中存在的问题及潜在的发展方向.
英文摘要：
Refractory metal silicide is the promising composition of the coating for ceramic insulation composites because of the high melting point,high emissivity and excellent oxidation protective ability at elevated temperatures.High emissivity coatings of ceramic tiles used in the major areas and the oxidation protective coatings on ceramic tiles used in high temperature regions are reviewed.Advantages and disadvantages of preparation technologies are introduced.The present problems and the potential development direction on the investigation of the coatings for ceramic composites are also proposed.
