The key phenomena controlling the properties of sprayed coatings are the heat and
momentum transfer between the plasma jet and the injected particles. Modern on-line …

Plasma spraying has become one of the most important thermal-spray technologies due to
low operating costs, high deposition rates, and a high efficiency. It is especially suitable for …

Control of the thermal spray process generally considers the monitoring of the mean in-flight
particle characteristics (ie, mean velocity and temperature) during the coating process. The …

Among the different coating technologies, a thermal spray has a leading position because of
its versatility: an extremely wide variety of materials can be deposited to protect back …

The standards of quality in the aerospace industry require a precise control of the thermal
spray process to insure a good reproducibility of the coating characteristics. Even if the …

The motion and heating of feedstock particles in the jet during plasma spraying have been
simulated using a theoretical model based on a CFD code. The main parameters affecting …

This paper is the continuation of previous work,[1] in which plasma fluctuations were shown
to produce significant time-dependent variations in the in-flight particle temperature and …

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 …

Plasma spraying is a complicated process involving many partly interdependent parameters,
which are in industrial spray environments difficult to optimise without laborious and time …

This paper presents what is our actual knowledge about sensors, used in the harsh
environment of spray booths, to improve the reproducibility and reliability of coatings …
