- 摘要：
- Abstract The displacement instability of the thermally grown oxide (TGO) under thermal
cycling is a fundamental source of cracking within the ceramic top-coat (TC) in a thermal
barrier coating system. The effect of TGO creep on TC cracking induced by cyclic instability
is numerically investigated in this work. Temperature-dependent elastic–plastic properties of
each coating layer are considered in a finite element analysis. A power law is adopted to
model the creep behavior of TGO and bond-coat (BC), and TGO growth at high ...
