abstract = {The Atmospheric Plasma Spray (APS) Process is a widely used
technique for manufacturing ceramic coatings with unique
properties for many applications, whereat the residual
stresses within these coatings are an important factor
affecting their performance. The coating formation is
characterized by the subsequent impingement of a large
number of more or less molten particles forming the so
called splats. Understanding the mechanisms connecting these
smallest structural elements with the overall coating
properties enables the specific design of the coating
process. In the present work, the correlation between
coating porosity, Young's modulus, and residual stress with
the particle melting was investigated. Therefore, single
splats were collected on mirror-polished substrates and
evaluated by identifying different types and their relative
fractions under various spray conditions. Microscopic
investigations were performed to obtain information on the
spreading behavior of the different splat types to establish
a relation to the coating properties. Furthermore, the
particles were characterized by in-flight measurement of
their temperature and the obtained results were evaluated in
terms of their degree of melting. This was compared with the
experimentally observed splat type amounts and finally
correlated to the investigated coating properties.},
