制备了一种具有自愈合功能的C/C复合材料抗氧化涂层,它主要由SiC和B4C、高熔点还原性氧化物等陶瓷细粉经简单工艺涂刷制成.通过动态氧气氛中的TGA试验、静态干燥空气中的氧化失重试验及扫描电镜、X射线衍射分析研究了其抗氧化和抗热震性能,试验结果显示,该涂层能承受1000℃以下40ml/min氧流量的动态氧化冲击;对应600～1000℃的静态氧化的平均氧化失重率介于10-8～10-6 g/(cm2·s)量级,涂层在1000℃以内的工作温度环境下具有良好的抗氧化能力;涂层试样经过10次热震循环后总的氧化失重为17.8%,在一定热循环范围内具有较好的抗热震性能;涂层试样的氧化失重率与氧化时间及热震次数具有非线性关系,表明该涂层具有自我愈合裂纹的功能.
