碳纤维增强碳化硅（C/SiC）复合材料是一种集高比强度和损伤容限于一体的轻质材料。对于高温应用，保护涂层必须提供抗氧化性和抗腐蚀性。文献资料介绍了各种适用于涂料应用的技术和材料。涂层的程序和条件，材料设计的限制有关的C/SiC复合材料的组分的反应性，新的方法和涂层系统的保护涂层材料的选择进行了检查。未来工作的重点是通过进一步的多层涂层系统和C/SiC复合材料的抗氧化能力在温度高达2073 K或更高的水蒸气中的优化。
Carbon fiber-reinforced silicon carbide (C/SiC) composites were well-established light weight materials combining high specific strength and damage tolerance. For high-temperature applications, protective coatings had to provide oxidation and corrosion resistance. The literature data introduced various technologies and materials, which were suitable for the application of coatings. Coating procedures and conditions, materials design limitations related to the reactivity of the components of C/SiC composites, new approaches and coating systems to the selection of protective coatings materials were examined. The focus of future work was on optimization by further multilayer coating systems and the anti-oxidation ability of C/SiC composites at temperatures up to 2073 K or higher in water vapor.
