摘　　要：热障涂层是航空发动机和地面燃气轮机提升工作效率、延长服役寿命的关键技术和重要手段。粘结层作为热障涂层系统中的重要组成部分,一方面可缓解陶瓷层和高温合金基体间的热不匹配应力,提高热障涂层系统热稳定性;另一方面,高温下通过生长一层致密且连续的Al_(2)O_(3)层,保护合金基体免受氧化和腐蚀。因此,粘结层性能直接决定了热障涂层系统的服役寿命。本文系统总结了传统粘结层材料、制备方法及其优缺点等方面的研究进展,同时介绍了新型高熵合金粘结层体系,重点关注其成分设计、结构及抗氧化性能等方面的研究现状及不足。最后,对粘结层材料的研究方向进行了展望。Thermal barrier coatings(TBCs)are widely used to protect the key components of areoand land-based turbine engines,which is a key technology and an important means to improve engines efficiency and extend service life.The bond coat,as an important component of the TBC system,can relieve the thermal mismatch between the ceramic topcoat and the superalloy substrate,and improve the thermal stability of the thermal barrier coating system.On the other hand,it protects the superalloy substrate from oxidation and corrosion at high temperatures by forming a dense and continuous of Al_(2)O_(3)layer.Therefore,the service life of the TBCs is predominantly dependent on the performance of bond coat.In this paper,the research progress on the conventional bond coat materials and preparation methods,as well as their advantages and disadvantages are introduced.The newly high-entropy alloy bond coat system is introduced with emphasis on the research progress of composition design,structure and oxidation resistance,as well as its deficiencies.Finally,the research trend of high entropy alloy bond coat materials is prospected.
