abstract = {In the atmospheric plasma spray (APS) process, micro-sized
ceramic powder is injected into a thermal plasma where it is
rapidly heated and propelled toward the substrate. The
coating formation is characterized by the subsequent
impingement of a large number of more or less molten
particles forming the so-called splats and eventually the
coating. In this study, a systematic investigation on the
influence of selected spray parameters on the coating
microstructure and the coating properties was conducted. The
investigation thereby comprised the coating porosity, the
elastic modulus, and the residual stress evolution within
the coating. The melting status of the particles at the
impingement on the substrate in combination with the
substrate surface condition is crucial for the coating
formation. Single splats were collected on mirror-polished
substrates for selected spray conditions and evaluated by
identifying different types of splats (ideal, distorted,
weakly bonded, and partially molten) and their relative
fractions. In a previous study, these splat types were
evaluated in terms of their effect on the above-mentioned
coating properties. The particle melting status, which
serves as a measure for the particle spreading behavior, was
determined by in-flight particle temperature measurements
and correlated to the coating properties. It was found that
the gun power and the spray distance have a strong effect on
the investigated coating properties, whereas the feed rate
and the cooling show minor influence.},
