abstract = {Emerging new applications and growing demands of
plasma-sprayed coatings have initiated the development of
new plasma spray processes. One of them is suspension plasma
spraying (SPS). The use of liquid feedstock such as
suspensions yields higher flexibility compared to the
conventional atmospheric plasma spray processes (APS) as
even submicron- to nano-sized particles can be processed.
This allows, e.g., achieving porous segmented or
columnar-structured TBCs or thin and dense coatings for gas
separation membranes. To exploit the potentials of such
novel plasma spray processes, the plasma-feedstock
interaction must be understood better.In this study,
decomposition and evaporation of feedstock material during
spraying were investigated, since particular difficulties
can occur with respect to stoichiometry and phase
composition of the deposits. Plasma conditions of SPS were
analyzed by optical emission spectroscopy (OES).
Experimental results are given, namely for gadolinium
zirconate (GZO) and for lanthanum strontium cobalt ferrite
(LSCF) deposition by SPS. Moreover, the applied OES approach
is validated by comparison with the simpler actinometry
method.},
