摘要
研究了不同SiC含量的Ti3SiC2/SiC复合材料在960℃下的恒温和循环氧化行为,实验表明,SiC含量对复合材料的抗氧化性能有着重要影响。对氧化后的样品进行了成分和显微组织形貌分析,其主要氧化产物为粗大的金红石型TiO2和精细的TiO2、SiO2(鳞石英)混合物。
The isothemal and cyclical oxidation behaviors of Ti3 SiC2/SiC composites with different contents of SiC in air were investigated at 960℃. The oxidation testing showed that the content of SiC was important to oxidation resistance of Ti3 SiC2/SiC composites. X_RD and SEM indicated that the scale was composed of an outer layer of coarse--grained TiO2 (rutile) and an inner layer of a mixture of fine-grained TiO2 and SiO2 (tridymite).
