中文摘要：采用料浆烧结法在不同石墨基体上制备了SiC涂层。详细研究了SiC涂层在不同石墨表面上的结构及其对不同石墨的抗氧化防护行为。结果表明：石墨基体的孔隙率和孔径尺寸决定着SiC涂层的结构，形成SiC梯度涂层的必要条件是石墨的孔径尺寸须处于0.1-0.5μm范围内；SiC梯度涂层有利于石墨基体抗氧化性能的提高。

外文摘要：A SiC coating was prepared on different graphite matrix using a simple slurry sintering method. The relationship between the microstructure and property of SiC coating and graphite substrates was experimentally investigated. It is found that the pore radius of graphite substrate has marked effect on the microstructure and property of SiC coating. A SiC gradient coating which is beneficial to improve the oxidation resistant of graphite, is expected to form on the surface of graphite substrates with the pore radius mainly in the range of 0.1-0.5 μm.
