摘　　要：研究了以ＴｉＣ颗粒增强的钛基复合材料的氧化特性。指出ＴｉＣ增强的钛基复合材料在６５０℃以上高温有着其它耐热钛合金不可比拟的高温抗氧化性能；ＴｉＣ／Ｔｉ的反应界面层有利于氧原子的扩散，使复合材料在６５０℃以下的氧化初期氧化速度较快；但在６５０℃以下经长时间保温，其氧化特性和其它耐热钛合金相似。The oxidizing dynamics of the TiC particle reinforcing composite of Ti matrix has been investigated The results show that the TiC particle reinforcing composite of Ti matrix has the excellent oxidation-resistant property above 650℃,which is beyond comparing with other high-temperature Ti alloys The TiC/Ti interface layer is beneficial to the diffusion ofoxygen atoms, which makes the composite oxidize fast at primary oxidizing below 650℃ The oxidizing dynamics of the composite is similar to that of otherhigh-temperature Ti alloys for long-time oxidizing below 650℃
