摘要：
TiAl alloy has the characteristics of low density, high specific strength and good creep properties, so it has a broad application prospect in aerospace, automotive industry and other fields. However, the lack of high temperature oxidation resistance limits their wide range of practical applications. The purpose of this review is to describe the research progress and mechanism of electrochemical oxidation, which is the surface modification method of oxidation protection of TiAl alloy, but it is not a general review of oxidation protection of TiAl alloy. The high temperature oxidation behavior and common protective measures of TiAl alloy are briefly introduced. The preparation method, formation process and protection mechanism of electrochemical oxidation coating are discussed in detail. Finally, the development trend of improving the high temperature oxidation resistance of TiAl alloy by electrochemical oxidation is prospected. © 2021, China Science Publishing & Media Ltd.
