Powder injection parameters such as gas flow, injection angle, and injector position strongly
influence the particle beam and thus coating properties. The interaction of the injection …

In plasma spraying, the particle velocity at the injector outlet has significant influence on the
particles' penetration into the plasma jet. The geometry of the injector and the flow rate of the …

Instabilities and fluctuations of the plasma jet in a thermal spray process can have a
significant influence on the particle in-flight temperatures and velocities, affecting the …

The coating characteristics of plasma sprayed layers are strongly related to the spray
parameters and the gun design which also determine the state of the sprayed powder …

The quality of plasma sprayed coatings depends strongly on substrate surface preparation,
especially roughness, grit residue, and oxidation stage; particle spray jet position and size …

The plasma spray process with solid feedstock, mainly ceramics powders, studied since the
sixties is now a mature technology. The plasma jet and particle in-flight characterizations are …

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 …

Plasma spraying is the process of injecting particles into a hot plasma plume where they are
heated and propelled towards a substrate forming a coating. The effects of major operating …

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 …
