abstract = {Emerging new applications and growing demands of plasma
sprayed coatings have initiated the development of new
plasma spray processes. One of them is plasma
spraying-physical vapor deposition (PS-PVD) filling the gap
between conventional liquid splat deposition and vapor
deposition methods like electron beam-physical vapor
deposition (EB-PVD). A second novel process is suspension
plasma spraying (SPS) enabling the processing of
submicron-sized feedstock by injecting suspensions into the
plasma jet. Both of these processes allow obtaining
particular microstructures which are not available by
conventional atmospheric plasma spraying (APS). They can be
very thin and dense layers as well as segmented or columnar
structured highly porous coatings.To exploit these
potentials, the plasma characteristics and the
plasma-feedstock interaction must be understood better.
Hence, plasma conditions at PS-PVD and SPS were studied by
optical emission spectroscopy (OES). Decomposition and
evaporation of feedstock material were investigated as well,
since particular difficulties can occur with respect to
stoichiometry and phase composition of the deposits. Some
experimental examples are given to demonstrate the
applicability of OES.},
