Modeling activities on plasma sprayed thermal barrier coating are presented. Through-process modeling of the APS deposition of a ZrO2 based TBC is described. A homogenization method is introduced to describe the mechanical properties of the resulting TBC. Moreover, simulations of interdiffusion and phase transformations of MCrAlY and intermetallic oxidation protection coatings on Ni-base alloy substrates are presented. Finally, damage simulations of oxidation protection coatings by fatigue cracks and by TBC delamination during thermocyclic loading are discussed.
