摘要：

The damage mechanisms of thermal barrier coatings are investigated using in-phase (IP) and out-of-phase (OOP) thermomechanical fatigue (TMF) tests. During IP testing, TMF damage is governed by the susceptibility of the coating to buckling, In OOP tests, cracking of the substrate controls life. Cracks initiate either at the unprotected surface of the substrate or within the bond coat. nucleated at defects formed during thermal exposure.
