| Abstract: |
| With the continuous improvement of service temperature, service life and thermal insulation performance of thermal barrier coating on turbine blades of advanced aeroengines, the development of ultra-high temperature, long life and high thermal insulation performance thermal barrier coating has become a research hotspot in the field of international high temperature protective coating. Oxide doped YSZ coating is the most likely thermal barrier coating material to replace YSZ coating on the surface of hot end components of aeroengine due to its good thermal performance. Therefore, the achievements and existing problems in the research of oxide doped YSZ thermal barrier coating was reviewed, the mechanism of the influence of different oxide doping on the properties of YSZ coating was clarified, and the current research progress on the preparation technology of this kind of coating at home and abroad was briefly described. It is proposed that the future research on thermal barrier coating should be based on further optimization of the design of polyoxide-doped YSZ coatings. The coupling mechanism of polyoxide doping is analyzed by computational simulation. At the same time, combining with the properties of the new generation of superalloy, a new thermal barrier coating system matching superalloy, bonding layer and ceramic layer is developed and the service behavior and failure mechanism are investigated from the two aspects of thermodynamics-kinetics, thus finally promoting the practical application of this coating. |
