Abstract

The goal of this project was to fully characterize the microstructure of the EB-PVD TBCs deposited on "shadow bar" cylinders and three turbine blades as a function of position in Pratt & Whitney's coater one as well as location on the substrate. Using image analysis software, data models were constructed for TBC thickness, density and angle of crystal growth. Additionally, crystallographic orientation was determined for the cylinder's as well as PW4000 2nd stage turbine blades using x-ray diffraction.
