Here TBC top coat failure and life time are considered as a two-step process, where step 1 is time to delamination macro-cracking and step 2 is time to through macro-cracking. This two-step failure...

For about the last two decades there has been an effort to produce a reasonable life time model for the thermal barrier coating systems (TBC) that are used in the gas turbine industry. However, recent advances in testing technology, namely acoustic e
