摘要
本文报告了C/C复合材料抗氧化涂层的研究与改进,由于在SiC基本涂层之上覆盖了新型的玻璃密封剂,材料的抗氧化性能提高了数十倍。这样的SiC涂层系统经受了长达30h以上的高温氧化试验和多种动态环境模拟试验而保持完整无损,显示了优良的性能和长的使用寿命。本文还对所研制的抗氧化C/C复合材料的力学和物理性能做了全面测试,并与美国航天飞机应用的RCC材料和ACC材料作了比较。
Research and improvement on oxidation resistant coatings for C/C composites have been described. Due to covering a type of new glass sealant on the basic SiC coatings,the oxidation resistant performance of materials raised one order of magnitude.After undergoing 30-hour high temperature oxidation and many environment simulating experiments,this SiC coating system still maintains excellent integrity.That shows the coating systems have advanced-performance and long life time.The mechanical and physical properties of oxidation resistant C/C composites have been measured and compared with RCC and ACC materials of USA.
