热障涂层主要作用在发动机的热端部件,可以减少油耗,提高效率,延长热端部件使用寿命. 热障涂层技术的高速发展使得航空发动机的性能得到了极大的提高,但是它在使用过程中存在着失效问题. 主要对陶瓷面层存在的高温烧结、热生长氧化物生长应力、高温热腐蚀和界面应力失配四种问题进行了论述,并针对具体问题提出了解决方案. 同时,对新型的低热导率热障涂层和应用在CMC基体上的热障涂层的研发情况进行了综述和展望.
Thermal barrier coating is mainly applied on the hot components of engine, which can reduce fuel consumption, in-crease efficiency and prolong the service life of hot components. The rapid development of thermal barrier coating technology has greatly promoted the improvement of aviation engine performance,but there exist some failure problems in using process. This arti-cle mainly discussed four problems of the YSZ thermal barrier coating, including high temperature sintering,TGO growth stress,hot corrosion in high temperature and mismatch of interfacial stress. In addition, it also introduced the solution of these problems. Fi-nally, this paper also reviewed and prospected the novel low-conductive TBC and the TBC which is currently applied on CMC matrix.
