Ti3AlC2材料的制备及其高温抗氧化性能研究
Preparation and High-temperature Oxidation Behavior of Ti3AlC2 Material
摘要
Abstract
High-purity Ti3AlC2 material was prepared by hot-pressing sintering using TiC, Ti and Al powders as raw materials with a mol ratio of TiC: Ti: Al = 2: 1: 1. The phase composition and microstructure of the products were studied by XRD and SEM. The results show that the materials were composed of Ti3A1C2 and TiC phases, TiC content was very small. The laminated Ti3A1C2 was well developed and uniform. The interrupted oxidation behavior of Ti3A1C2 at 900 ℃ for 30 hours in air was also investigated. The oxidation kinetics followed parabolic law. The oxidizing layer was composed of TiO2 and Al2O3 phases, which contributed to improve the oxidation resistance.关键词
