Abstract
The crystallographic texture of EB-PVD TBCs has been experimentally determined by pole figure analysis and X-ray diffraction. It was found that the TBC coating deposited on a stationary flat surface directly above an ingot or between the two ingots and off center exhibited single crystal texture. Coatings deposited at the far corners of the coating chamber revealed a fiber texture with 〈111〉 column growth direction. The Bragg–Brentano X-ray diffraction analysis revealed a variety of textures (i.e. crystallographic planes that are parallel to the substrate surface) with the most predominant planes being the (220), (311), (420) and (620).
