平纹编织C/SiC复合材料在1300℃模拟环境中的疲劳行为
Abstract:
通过拉–拉疲劳试验并结合电镜扫描观察,对比研究平纹编织C/SiC陶瓷基复合材料在1300℃惰性气氛环境和两种腐蚀气氛环境中的疲劳行为。结果表明由于高温氧化腐蚀的作用,1300℃下腐蚀气氛环境中C/SiC陶瓷的抗疲劳性能明显比惰性气氛环境差,而且氧气和水分含量越高,陶瓷基复合材料在腐蚀气氛环境中的抗疲劳性能越差。疲劳载荷对氧化腐蚀起着推动作用,疲劳载荷越大裂纹宽度越大,不同的裂纹宽度对应着不同的氧化机制,从而产生不同的氧化形貌。腐蚀气氛环境中的氧气含量决定着C纤维的氧化速度。水分含量低时,于1300℃在涂层表面生成无定形态的SiO2对裂纹具有封填效果从而提高材料寿命;水分含量高时不仅促使SiO2大量析晶减弱其封填效果,而且其会与SiO2反应生成气态产物,大量消耗涂层,降低材料寿命。
