Abstract The effects of three factors, including the power supply, the arc behaviour in the arc channel and the fluid dynamic process of the jet, on a plasma spraying jet have been experimentally detected by means of spectroscopic diagnostic techniques. The fast Fourier transform method has been applied to the analysis on the arc voltage and spectral line intensity of the jet. The three factors have been studied and distinguished from each other.
