摘要：
The degradation of thermal barrier coatings is closely linked to their spalling resistance which depends on the stability of the protective oxide scale produced by oxidation of the bond-coat. This study deals with a characterisation of the oxide layer, its interfaces with the bond-coat and the ceramic and their evolution during isothermal oxidation at 1,100 degrees C. The microstructural evolution of the bond-coat, the outer part of the superalloy and the ceramic layer was also studied.
