In the Plasma Spray-Physical Vapor Deposition (PS-PVD) process, columnar structured coatings are deposited mainly from the vapor phase due to the intensive evaporation of the feedstock powder. This paper highlights the application of electron backscatter diffraction (EBSD) for the characterization of columnar structured ceramic PS-PVD coatings. The growth processes of PS-PVD coatings could be elucidated, developing from small equiaxed crystals to large columnar crystals. Furthermore, the main effect of the torch swing on coating deposition could be the interruption of crystal growth and thus repeated nucleation. This may have a similar effect as slowly rotating the substrate in Electron Beam-Physical Vapor Deposition (EB-PVD).

在等离子喷涂物理气相沉积（PS-PVD）工艺中，由于原料粉末的强烈蒸发，圆柱状结构涂层主要从气相中沉积。本文着重介绍了电子背散射衍射（EBSD）在表征柱状结构PS-PVD陶瓷涂层中的应用。可以阐明PS-PVD涂层的生长过程，即从小的等轴晶体发展为大的柱状晶体。此外，割炬摆动对涂层沉积的主要影响可能是晶体生长的中断，从而导致反复成核。这可能与在电子束物理气相沉积（EB-PVD）中缓慢旋转基板具有相似的效果。
