摘要

随着航空发动机向着高效率、高推重比方向发展，对发动机热端部件表面应用的热障涂层提出更高要求。传统 YSZ 材料已不能满足更高承温温度和更好隔热能力的需求，新型热障涂层材料的开发和应用受到越来越多国内外学者的关注。锆酸钆材料热导率低，相变温度高，热膨胀系数大，是最具应用前景的热障涂层陶瓷材料之一。基于已公开发表的文献，详细介绍了锆酸钆热障涂层的研究进展。首先，简要介绍了热障涂层材料及制备工艺的研究现状；其次，分别对锆酸钆材料的基本性能与不同工艺制备的锆酸钆涂层性能进行详细论述；最后，探讨了锆酸钆材料存在的问题及采用等离子喷涂 - 物理气相沉积制备锆酸钆涂层的应用前景。

Abstract

With the development of aero-engine towards high efficiency and high thrust weight ratio

higher requirements are put forward for the thermal barrier coatings applied on the surface of engine hot end parts. For YSZ materials can not meet the requirements of higher temperature and better thermal insulation

the development and application of new thermal barrier coating materials are attracting more and more attention worldwide. Gadolinium zirconate is one of the most promising ceramic materials for thermal barrier coatings due to its low thermal conductivity

high phase transition temperature and high thermal expansion coefficient. Based on the published literature

the research progress on gadolinium zirconate thermal barrier coatings is summarized in detail. Firstly

the research status of thermal barrier coating materials and preparation technology is briefly introduced. Secondly

the properties of gadolinium zirconate materials and the properties of gadolinium zirconate thermal barrier coating prepared by different processes are expounded in detail. Finally

the existing problems of gadolinium zirconate materials and the application prospect of preparing gadolinium zirconate coating by plasma spray-physical vapor deposition (PS-PVD) are discussed.
