To obtain reproducible and reliable plasma sprayed coatings, it is mandatory to achieve an
on-line control of a few well chosen parameters. Among them the substrate and coating …

This paper presents what is our actual knowledge in the development of the on-line control
of the plasma spray process. First the influence of the different parameters on coating …

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 …

A new measurement technology in plasma spraying has been established at SULZER
METCO AG, Switzerland. Based on the principle of C. Moreau, CNRC, it is now possible to …

An attempt to develop a theory for the calculation of the temperature distribution in a plasma-
sprayed coating is presented. This theory takes into account both the physical properties of …

Thermal spray technology became established in various parts of industry (eg aircraft
industry, medical industry etc.). Some of the applications are highly sensitive, therefore the …

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 …

Plasma spray technology, with its great number of coating-substrate combinations, satisfies
the demand of new materials needed to work in severe environments. After a general …

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 …

When spraying is conducted in the ambient atmosphere, the entrainment of air cools down
the plasma jet and affects its expansion. It may also cause the oxidation or the chemical …
