研究了用原位反应法制备的ＴｉＣ颗粒增强铸造Ｆｅ－２６Ｃｒ－１４Ｎｉ基复合材料在１０００℃和１２００℃下的抗氧化性能。结果表明，ＴｉＣ的存在使复合材料在氧化初期具有短路扩散效应，其氧化动力学曲线符合对数增长规律；氧化膜由棱角多面体状的Ｃｒ２Ｏ３组成，在１０００℃下，复合材料具有理想的氧化膜结构和优良的抗氧化性；温度再提高，氧化物尺寸增大，氧化膜致密度降低；在１２００℃下，复合材料抗氧化性与基体合金相近。
The oxidation resistance of Fe-26Cr-14Ni-based composite reinforced by TiC particles reinforced by in-situ reaction at 1000 ℃ and 1200 ℃ was studied. The results show that TiC has short-circuit diffusion effect at the initial stage of oxidation and the oxidation kinetics curve accords with the law of logarithmic growth. The oxide film consists of Cr2O3 with angular polyhedron. The composite has the ideal oxide film Structure and excellent oxidation resistance. With the increase of temperature, the size of oxide increases and the density of oxide film decreases. At 1200 ℃, the oxidation resistance of the composites is similar to that of the matrix alloy.
