A newly designed plasma electrode-type spray gun, which can inject the spraying material into the center of the arc column, has been developed. In order to demonstrate the application feasibility of this plasma spray gun to thermal processing, the effect of liquid material loading on the characteristics of the arc and plasma jet was clarified. The liquid material was C2H5OH. It was found that the spray gun operated stably with liquid loading, and the jet power was effectively controlled by changing the arc current. It was clarified that this proposed new type plasma spray gun would be very useful device for various material processing.
