A newly designed cross electrode-type plasma spray gun, which can inject the spraying materials into the arc column, has been developed. In order to demonstrate the application feasibility of this spray gun to formation of Ti-Al functionally graded coatings, the performance characteristics of this spray gun and the structure and composition of formatted coatings were investigated. It was clarified that this spray gun was operated stably during spraying, jet power was easily controlled by arc current and the high quality Ti-Al functionally graded coatings was formatted under the following conditions: the jet power of over 7kW and Ti powder diameter distribution of 54-63 μm. It was also found that the structures of coatings were controlled by Ti powder diameter.
