摘要
TiAl基金属间化合物由于其密度低、高温性能好,越来越受到人们的重视。简单介绍了TiAl基合金研究的重点以及研究现状,对TiAl系合金高温氧化机理进行了分析,重点讨论了高温防护涂层发展过程。
TiAl-base intermetallic compounds have received considerable attention as high-temperature structural materials due to their low density and high specific strength. However, poor oxidation resistance of TiAl must be overcome before it can be used in practice at elevated temperature In this paper, present state of oxidation and oxidation mechanism are discussed. The protection mechanism is focused on. Finally, the research and development direction is discussed.
