Abstract
The mechanism of competition between different interfacial cracks in a thermal barrier coating system (TBCs) is experimentally and numerically investigated. In-situ three-point bending tests were conducted on TBCs samples having different top coats (TC) and bond coats (BC). The competition between cracks at TC/BC and BC/substrate interfaces in the TBCs was observed, and then analyzed to elucidate the mechanism. Different fracture modes of the TBCs have been defined. A failure map based on the modulus ratio and thickness ratio is numerically established, which agrees well with the experimental results.
