Abstract

As ceramic thermal barrier coatings (TBC) are used in more critical applications in advanced engines, knowing basic physiproperties of TBC's is essential for design and reliability assessment. In particular, knowledge of thermal conductivity is cruciin advanced gas turbine airfoil design to allow more precise part temperature and life assessment. As physical properties ardifficult, costly, and time-consuming to measure directly, an alternate strategy is to calculate these properties from thecomplex coating microstructure. In this study a finite-difference code (TBCTOOL) and a finite-element code (OOF) were useto determine the thermal response from electron-beam physically vapor deposited (EB-PVD) TBC microstructures. Resultsbe given comparing the finite-difference & the finite-element simulations. Effects of simulation boundary conditions and ofimage sectioning protocols will be discussed.
