Investigation on crystal orientations in EB-PVD YSZ coatings under different substrate rotation mode

The crystal orientations in YSZ coatings produced by electron-beam physical vapor deposition (EB-PVD) were analyzed. Two different coatings have been prepared by distinct substrate rotation mode, including S1 prepared by the conventional method and S2 prepared by controlling the rotation and oscillation of the substrate. The substrate rotation modes were implemented by a rotating holder. Based on investigations of crystallographic microstructure and texture characterization methods indexed with reference to be tetragonal lattice symmetry, it concluded that S1 has an [001] in-plane orientation, whilst S2 has an [001] out-of-plane orientation.
