摘　　要：高温合金是一种复杂组元多相组织材料,在高温下的热腐蚀行为是制约其发展的重要因素。国内外学者对高温合金的热腐蚀性能做了大量研究,先后提出了多种腐蚀机理模型,但对于不同种类高温合金腐蚀机制间的相互关系仍缺乏成熟的理论表述。从高温合金的特点和用途对热腐蚀的影响因素进行了综述,并对目前高温合金主要的涂层、预氧化等耐热腐蚀防护措施进行了讨论。最后,从实际应用角度展望了未来提高合金热腐蚀性能的方法。The thermal corrosion properties of superalloy had done a lot of research by the domestic and foreign scholars, a variety of corrosion mechanism model was proposed, but still lack the mutual theory to describe the relationship between different kinds of superalloy corrosion mechanism. In this paper, the influence factors of thermal corrosion from the characteristics and applications of superalloy were reviewed, the main coating and preoxidation corrosion protection measures of superalloy were discussed. Finally, the method of improving the thermal corrosion performance of the superalloy is forecasted from the practical application perspective.
