abstract = {Plasma spray-physical vapor deposition (PS-PVD) is a novel
coating process based on plasma spraying. In contrast to
conventional methods, deposition takes place not only from
liquid splats but also from nano-sized clusters and from the
vapor phase. This offers new opportunities to obtain
advanced microstructures and thus to comply with the growing
demands on modern functional coatings. Thin and dense
ceramic coatings as well as highly porous columnar
structures can be achieved, offering novel opportunities for
the application of thermal spray technology.This study
describes process conditions, which are relevant for the
formation of particular microstructures in the PS-PVD
process. Following the structure of the process, the
feedstock treatment close to the plasma source, plasma
particle interaction in the open jet and the formation of
coating microstructures on the substrate are covered.
Calculated results on the plasma particle interaction under
PS-PVD process conditions were found to be in good agreement
with OES results and microstructural observations. They show
that the feedstock treatment along the very first trajectory
segment between injector and jet expansion plays a key
role.Varying the plasma parameters, feedstock treatment can
be controlled to a broad extent. Consequently, the manifold
nature of the feedstock species arriving on the substrate
enables to achieve various coating microstructures. As
examples, application specific features of PS-PVD coatings
are reported for strain-tolerant thermal barrier coatings as
well as for gas-tight oxygen transport membranes with high
mixed electronic-ionic conductivity.},
