Özet:

 Thermal barrier coatings TBC have been developed to reduce the surface temperature of hot components in gas turbine engines. To get superior oxidation and mechanical properties, The Yttria Stabilized Zirconia YSZ top coat and β-NiAl bond coat are deposited by Electron Beam Physical Vapor Deposition EB-PVD and Chemical Vapor Deposition CVD processes, respectively. In this study, after structural characterization of the TBC formed on the directionally solidified DS CM247LC superalloy, the nanomechanical properties of the top and bond coats were determined using the nanoindentation technique. The results showed no significant differences in their elastic modulus despite the more than two times higher hardness of the top coat than the bond coat 18.4 GPa and 7.2 GPa, respectively. Energy Dispersive Spectrometry EDS equipped with Scanning Electron Microscope examinations revealed that Al and N- and N-rich zones within the bond coat have an underlying diffusion zone. In addition, thermal-grown oxide TGO film was detected at the interface of the top and bond coat.
