| 摘 要： | 热障涂层（TBC）被广泛应用于热端金属部件表面，使其免受高温气体侵蚀，其微观组织结构及服役性能与制备工艺和服役状态密切相关并相互作用。本文从热生长氧化物（TGO）增厚、相变、烧结等方面讨论了各种应力诱因导致的TBC失效机理，综述了目前常用于陶瓷层柱状结构制备的方法及其在缓和TBC服役过程中应力的应用。由于TBC制备工艺及服役条件不尽相同，通过与标准TBC比较，评价了不同工艺下制备的TBC使用寿命，总结了柱状结构TBC的长寿命服役机理。本文综述了柱状热障涂层的应力源、微观结构、制备工艺和使用性能的相互作用关系，为高性能TBC设计提供了参考。

| Abstract: | The thermal barrier coatings (TBCs) are employed to protect metallic components from high temperature gas, and their microstructure and service performance are closely related to and have the mutual effect with the preparation process and service condition. This research reviews TBCs failure mechanisms caused by different stress inducements from the perspective of thermally grown oxide (TGO) thickening, phase transformations, and sintering. Subsequently, the preparation methods of TBCs with columnar structure are summarized, as well as their functions of releasing stress during TBC service. Although the preparation process and service conditions are different, the lifetimes of TBCs prepared by different methods are evaluated by comparing with that of the standard TBCs. The long lifetime service mechanism of TBCs with column structure is summarized. This research reviews the interaction effects among the stress source, microstructure, preparation process, and service performance of TBCs, providing guidance for the advanced and durable TBCs design. |
