Thermal Barrier Coating Spallation on Gas Turbine

[Pipoy04]

Dear Experts,

I would like to know if there's acceptance criteria for the TBC spallation of gas turbine blades?

Is there any reference codes or standards?

Usually this falls under the turbine OEM for guidance.

And your OEM really, really, really does NOT want you allowing ANYBODY else to analyze his turbine blade and vane designs, ceramics, cooling air flow, and - most espcially - any problems you (and he) may be having with his blade and vane designs!
