In spite of the fact that plasma spraying is a commonly used technique for coating
elaboration, it remains important to follow in time the characteristics of the arc jet delivered …

The development of coating formation processes involving electric arcs depends on process
stability and the capacity to ensure a constant reproducibility of coating properties. This is …

This work is devoted to the instabilities occurring in a plasma torch, such as those found in
plasma spraying. These instabilities are responsible for a lack of reproducibility of coatings …

The control over coating quality in plasma spraying is partly dependent on the arc and jet
instabilities of the plasma torch. Different forms of instabilities have been observed with …

The damaging of the electrodes during spraying can affect the reproducibility of the plasma
spray process. Indeed, this may influence the plasma characteristics and the energy transfer …

The control over coating quality in plasma spraying is partly dependent on the arc and jet
instabilities of the plasma torch. Different forms of instabilities have been observed with …

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 …

Abstract Direct current Suspension Plasma Spraying (SPS) allows depositing finely
structured coatings. This article presents an analysis of the influence of plasma instabilities …

The plasma spray process is widely used to produce thick coatings by the successive pilling
of particles deposited in a molten or semi-molten state on a prepared substrate. However …

In this paper, two long-term experiments are conducted in order to investigate the evolution
of the arc root fluctuations and the evolution of the in-flight particle state during plasma …
