A newly designed cross electrode type plasma spray gun, which is consisted of the cross electrode type arc plasma generator and the feed ring to inject the processing materials into the arc column, has been developed. The effects of the operating ambient pressure, the carrier gas injection and powder loading on the characteristics of the arc and plasma jet were studied experimentally. It was found that the jet power was effectively controlled by changing the arc current and that a stable and clean plasma flow was generated over a wide range of processing conditions. Therefore it was confirmed that this proposed new type plasma spray gun was very useful device for various plasma processings.
