| Abstract: | Formation and evolution of the thermally grown oxides(TGO) have great effect on the properties of thermal barrier coatings( TBCs), suggesting a sticking point for analyzing TBCs failure and prolonging the life of TBCs. The research progress of the oxidation behavior of TBCs worldwide is summarized,including oxidation kinetics of bond coating(BC),composition,structure and evolution of TGO,and transformation from metastable Al2O3 to stable Al2O3. Effects of elements from BC on the morphology and structure of TGO is analyzed,as well as the elements diffused from substrate. Idea for research of BC-oxidation behavior and methods for properties-improvement of TBCs are indicated. |
