| Paper description | Abstract The interfacial failure mechanism of the thermal barrier coating system (TBCs) was numerically investigated by considering the role of mixed oxides (MO), which was induced by the discontinuous α-Al 2 O 3 at the interface between top and bond coatings. It is shown that MO has a significant effect on the interface integrity. High growth rate of MO will induce the initiation and propagation of interface cracks and eventually results in the debonding of ceramic coating. The high coverage ratio of MO at the interface will accelerate the ... |
