摘要:
研究了原位反应法制备的TiCP/3Cr13钢基复合材料在850 ℃和950 ℃的抗氧化性能.结果表明:与基体合金相比,在850 ℃条件下,由于TiC颗粒的引入,复合材料在氧化初期具有短路扩散效应,稳定阶段它的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,复合材料具有理想的氧化膜结构和优良的抗氧化性能; 在950 ℃条件下,氧化膜由粗大的FeO·Cr2O3组成,氧化膜致密度下
Abstract:
The oxidation resistance of TiC particulate reinforced 3Cr13 matrix composites prepared by in-situ process at a temperature of 850 ℃and 950 ℃has been investigated, the results showed that, compared to 3Cr13 matrix, the short path diffussional effect is caused by TiC phase at initial oxiding stage,the cruves for oxiding kinetics of comoposite agrees with the law of logarithmic growth. The oxide film consists of polyhedron-like Cr2O3,the composite has an ideal structure of oxide film and excellent oxidation resistance at 850 ℃. The oxidation resistance of composite increases a little at 950 ℃ due to the decrease in compactivity of oxide film and the increase in size of (FeO·Cr2O3) oxide.
