摘要

摘要: 目的为了梳理燃气轮机热障涂层服役过程中的高温腐蚀问题，方法对燃气轮机热障涂层腐蚀类型和提高抗腐蚀性能的方法分别进行了归纳分析，并展望了提高热障涂层抗腐蚀性能的发展方向。结果经归纳分析，燃气轮机热障涂层腐蚀类型主要包括：陶瓷层高温相变、粘结层氧化、盐雾腐蚀、CMAS腐蚀以及燃料杂质腐蚀。提高热障涂层抗腐蚀性能的方法主要有：发展新的抗高温腐蚀涂层材料、进行涂层表面防腐处理、改变涂层系统结构以及提高燃气轮机辅助清洁功能。结论未来开发性能优异的新材料仍是提高热障涂层抗腐蚀性能的主要方向，而改进涂层结构设计、材料纳米化对提升热障涂层抗腐蚀性能有很大潜力。随着陶瓷基复合材料的发展，对涂层的高温腐蚀研究将逐步从热障涂层转向环境障涂层（EBC）。

Abstract: The review was done in order to make clear the problem of the hot corrosion of the Thermal Barrier Coatings (TBCs) during gas turbine serving. This paper summarizes the factors resulting from the hot corrosion of TBCs during turbine service and classifies methods for enhancing the corrosive resistance of TBCs. A prospective methodology for improving corrosion resistance is also formulated. The main types of corrosion coating include phase reaction, oxidizing of the bond coating, salt-fog corrosion, CMAS corrosion and fuel impurity corrosion. So far, methods for improving the corrosion resistance of TBCs include developing new coating materials, anticorrosive treatment on the surface of TBCs, modifying the stacking configuration and improving the cleansing functions of the gas turbines. In the future, developing new materials with excellent performance will still be the main direction for boosting the improvement of the hot corrosion resistance of TBCs. Simultaneously, improving the tacking configuration and nanotechnology of TBC coatings are potential approaches for improving corrosion resistance. With the development of a Ceramic Matrix Composite (CMC), the focus of the hot corrosion of TBCs may turn to that of Environmental Barrier Coatings (EBCs).
