      abstract     = {By Plasma Spray-Physical Vapor Deposition (PS-PVD), major
                      fractions of the powder feedstock can be evaporated so that
                      the coating builds up mainly from vapor phase. In this work,
                      the deposition mechanisms at different PS-PVD conditions
                      were investigated. Depending on the plasma flow conditions
                      and the substrate temperature, the columns in the coatings
                      possess successively pyramidal, cauliflower, and lamellar
                      shaped tops. In addition, the different microstructures show
                      characteristic crystallographic textures, in which different
                      in-plane and out-of-plane orientations were observed by pole
                      figures. Based on investigations by electron back-scatter
                      diffraction (EBSD), the overall coating growth process can
                      be roughly divided into three subsequent stages: equiaxed
                      growth, competitive growth, and preferential growth.
                      Influences of diffusion and shadowing on final coating
                      microstructure and orientation were discussed. The formation
                      of equiaxed grains was proposed to be caused by high
                      nucleation rates, which are probably induced by large
                      undercooling and super-saturation at the beginning of
                      deposition. The preferential growth orientation was
                      preliminarily explained based on an evolutionary selection
                      mechanism.},
