摘    要:全面综述国内外TiAl基合金体系高温氧化机理及其防护研究进展,特别是20世纪90年代以来的研究情况。主要阐述TiAl系金属间化合物分类及其应用、TiAl基合金高温氧化行为、氧化膜结构及其形成、氮效应、表面效应、Z相的形成及其对氧化行为的影响,合金化和涂层防护方法及其机理、近年来出现的新表面处理技术以及传统表面处理技术在TiAl基合金抗高温氧化防护方面的应用,对各种防护方法的特点及应用范围进行对比分析,并对该领域研究的发展趋势进行展望。

Abstract: The research progress at home and abroad of the high-temperature oxidation behavior and protection of the TiAl-based alloy, especially after 1990s, was reviewed. The classification and the applications, the high temperature oxidation behavior, the formation and structure of the oxidate layers, the formation and influence of nitrogen effect, surface effect and Z phase on oxidation behavior, the bulk and surface alloying protection and its mechanics, the coating protection and its mechanics of TiAl-based alloy, the formation and structure of the oxidation layers, the nitrogen effect, surface effect, the formation of Z phase and the effect of it on oxidation behavior, the alloying and coating protection of TiAl-based alloy, new surface treatment technologies and traditional surface treatment technologies reused to improve the high temperature oxidation resistance of the TiAl-based alloy and the future development of this area were reviewed. The characteristic and applications of the different protection ways were also discussed.
