• 論文の詳細を見る

• The paper presents the experimental and theoretical investigation on the thermal fatigue failure in thermal barrier coating (TBC) system. Laser heating method was used to simulate the operating state of TBC system. The non-destructive evaluation such as acoustic emission (AE) detect was used to study the evolution of TBC system damage. Micro-observation and AE detect both revealed that fatigue crack was in two forms : surface crack and interface delamination. Theoretical model on thermal stresses fields and interface delamination cracking in TBC system at operating state is proposed. The combined effect of plastic deformation and creep of ceramic coating as well as thermal growth oxidation (TGO) and temperature gradient in TBC system was considered in the model.
