Abstract

Current plasma spray coatings will contain 5 to 15% porosity. The proposed project will examine changes in the plasma gun design to decrease the porosity of the gas- deposited coating. A decrease in coating porosity is expected to increase the hardness and improve the corrosion resistance of the coating. With this study a more wear resistant efficient coating will be available. Although a similar process is available in coaxial spraying, our studies show possible improvements upon the coaxial method.
