Electric arc dynamics in plasma torch affects plasma jet stability and consequently, coating properties. Depending on plasma torch design, voltage fluctuations can vary from 100 % to only a few percent of the mean voltage. Particularly, cascaded-anod

Anode erosion is a common concern in dc plasma spray torches. It depends largely on the heat flux brought by the arc and the dimensions, residence time, and mode of the arc attachment to a given location on the anode wall. This paper compares anode a
