【摘要】 C/C复合材料的高温氧化性能限制了其在高温领域的更广泛应用。简要介绍了C/C材料的氧化机理,综述了两种主要的抗氧化方法,即基体改性和涂层技术;并就涂层体系的要求、基本结构和影响因素作了详细介绍,同时对C/C复合材料抗氧化研究发展的趋势提出了一些见解。更多还原

【Abstract】 Carbon/Carbon composites tend to be oxidated at high temperature, which "restricts their use in high-temperature applications. In this paper oxidation mechanism and two methods for improving oxidation resistance (oxidation resistance coating technique and oxidation resistance matrix modification technique) are reviewed. The requirements, basic structure and influencing factors for coating systems are also described. Finally future directions of carbon/carbon composites with oxidation resistance are outlined.更多还原
