Oxidation Properties of ZrB2-20vol.%SiC-10vol.%BN Ceramic Composite at 1200℃

摘要：

　　Dense ZrB2-20vol.%SiC-10vol.%BN (ZSB) ceramic composites by introducing BN as the third phase are fabricated through hot pressing sintering under inert gas protected.The static oxidation behavior of the ZrB2-SiC-BN ceramic composite at 1200℃ in air is analyzed using differential thermal analysis technique,and the surface morphology of the composites after oxidation at 1200℃ is examined using scanning electron microscopy along with energy dispersive spectroscopy.The microstructure change and oxidation behaviors of the ZrB2-SiC-BN ceramic composite are investigated.The effect of BN grain size is analyzed and the oxidation mechanism in ceramic composites is discussed correspondingly.
