Abstract: In this paper, a high pressure turbine (HPT) blade was analyzed under an extreme condition by Computational Fluid Dynamics (CFD) simulation. Nickel alloy CMSX10 (69.6Ni2Cr3Co0.4Mo5W6Re8Ta0.03Hf0.1Nb0.2Ti5.7Al), NiCrAlY and ZrO2Y2O3 were used as the blade, bond coating and top coating materials respectively. Different top coating thicknesses would be applied onto the blade and analyzed via software ANSYS Fluent 14.5 to estimate the optimum coating thickness. Without considering the microstructure of the applied materials, thickness about 0.4mm top coating could help the HPT work at a lower temperature and pressure environment if a 0.25mm bond coat is used.
