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 …

Coating quality is affected by arc and plume instabilities during plasma spraying. In closed
chamber plasma spraying, gradual drift is one of the intermediate instabilities, which is …

In direct current (dc) plasma spray torches, the dynamic behavior of the arc attachment at the
anode nozzle results in arc voltage fluctuations and correspondingly power fluctuations. The …

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 …
