- 摘要：
- Abstract Failure of thermal barrier coating (TBC) system is associated with the morphological
imperfection of thermally grown oxide (TGO) layer. The objective of this work is to
numerically investigate the crack nucleation and propagation in TBC system upon thermal
cycling based on a cohesive zone model, in which TGO thickness imperfection effect is
incorporated. The results show that TGO/BC (bond coat) interface is subjected to high tensile
stress in the vicinity of TGO thickness imperfection during thermal cycling, thereby ...
