abstract = {The residual stresses within plasma-sprayed coatings are an
important factor that can influence the lifetime as well as
the performance in operation. The investigation of stresses
evolving during deposition and post-deposition cooling for
atmospheric plasma spraying of yttria-stabilized zirconia
coatings using in situ measurement of the samples curvature
is a powerful tool for identifying the factors that
contribute to stress generation. Under various spray
conditions, the first deposition pass leads to a
significantly larger increase in samples curvature than the
subsequent passes. It is shown in this work that the amount
of curvature change at the onset of spraying is
significantly influenced by the spray conditions, as well as
by the substrate material. More information on the origin of
this steep curvature increase at the onset of spraying was
obtained by single splat experiments, which yielded
information on the splat bonding behavior under various
conditions. A comparison of the compressive yield strength
for different substrate materials indicated the influence of
substrate residual stress relaxation. Residual stress
measurements using the incremental hole-drilling method and
x-ray diffraction confirmed that the coating deposition
affects the substrate residual stress level. The yield
strength data were combined with the substrate near-surface
temperature during deposition, obtained by finite element
simulations, and with the measured residual stress-profile.
This revealed that residual stress relaxation is the key
factor for the initial curvature increase.},
