摘　　要：C/C复合材料在高温有氧环境中易氧化的缺点一定程度上影响了它在航空航天领域的应用与推广,抗氧化涂层技术是提高其高温长时间抗氧化性能最直接有效的方法。本文综述了近年来国内外C/C复合材料高温抗氧化涂层在玻璃、贵金属、陶瓷等涂层体系方面的最新研究成果;在分析介绍C/C高温抗氧化涂层传统制备工艺优缺点及应用情况的基础上,进一步总结了高温抗氧化涂层制备技术最新研究进展;并对已开发的抗氧化涂层体系适用环境及应用现状进行了深入的评述。最后针对C/C复合材料1 800℃以上的超高温抗氧化防护问题,指出了目前研究中存在的问题及未来应重点努力发展的方向。The drawback of easy oxidation for carbon/carbon （C/C） composites has limited their application as structural materials in aerospace field. The oxidation protective coating is one of the most effective methods that can realize the long term oxidationprotection for C/C composites at high temperatures. The recent development of oxida- tion protective coating materials for C/C composites, including glass, metal and ceramic coatings were reviewed. The advantages and defects of traditional preparation technologies as well as their application were analyzed and summa- rized. New advances in development of coating technologies were also introduced, and then, the suitable service envi- ronment and recent application of different coating systems were clarified. To meet the ultra high temperature oxidation protection for C/C composites above 1 800~C, the problem in recent study and the potential development directions in the future were proposed.
