In recent years, the interest in on-line diagnostic methods for thermal spraying has been
increasing. The particle in-flight properties can be determined using such methods. One of …

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 …

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 …

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

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 …

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 …

An approach based on a fuzzy logic controller was implemented to control and regulate the
atmospheric plasma spray processing parameters (arc current intensity, total plasma gas …

Al2O3 coating is deposited using a low power plasma torch with a novel hollow cathode
through axial powder injection under a plasma power up to several kilowatts. The effects of …

The role of particle injection velocity in influencing the nature of alumina coatings obtained
by plasma spraying was studied. Previously reported process chart obtained by …
