The plasma-spray process features complex plasma-particle interactions that can result in
process variations that limit process repeatability and coating performance. This paper …

Controlling particle state is important to not only achieve the required microstructure and
properties in coatings but also to clearly isolate and understand the role of other clusters of …

The wear state of the different gun parts can affect the reproducibility of the plasma spray
process. Indeed, this may influence the plasma characteristics and the energy transfer to the …

This paper discusses the requirements of sensors that could be used both for advanced real-
time control as well as manual torch operator control of plasma spray processes, and …

Publisher Summary Plasma spraying is a process in which finely divided metallic and
nonmetallic materials are deposited in a molten or semi-molten state on a prepared …

This paper describes a new optical sensing device for on-line monitoring of the temperature,
velocity and trajectory of in-flight particles during industrial coating production. Thermal …

Advanced coatings deposited by plasma spraying are used in a large variety of industrial
