| Abstract: |
| Thermal barrier coating is mainly applied on the hot components of engine, which can reduce fuel consumption, increase 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 article 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. Finally, this paper also reviewed and prospected the novel low-conductive TBC and the TBC which is currently applied on CMC matrix. |
