The goal of this project was to further the understanding of TBCs deposited by EB-PVD by Pratt & Whitney. First Pratt & Whitney's coater one was re-qualified. After that a fixture was designed to permit blade positioning on the x, y and z-axes and also allow for blade rotation. Finally the coating qualities were studied. Crystallographic orientation was determined using x-ray diffraction, column growth angles were calculated and surface and column microstructure were analyzed using SEM.
