Oxidation Behavior of Ti3SiC2-SiC Ceramic Composites
The high temperature oxidation behaviors of the Ti3SiC2-SiC ceramic composites fabricated by in situ synthesis under hot isostatic pressing were studied by DSC. The results show that the growth of the oxide scales on Ti3SiC2-SiC ceramic composites obeys a parabolic law in air. The oxidation resistance at 1400°C is better than that at 1200°C for long time. The oxidation resistance of the Ti3SiC2-SiC ceramic composites is much higher than that of monolithic Ti3SiC2. The mechanism of oxidation of Ti3SiC2-SiC ceramic composites is discussed.
