Slurry plasma spraying is gaining greater interest for emerging applications such as solid oxide fuel cells, new thermal barrier coatings, and next generation environmental barrier coatings. Mettech developed an axial injection plasma process coupled with automatic slurry feed system, and demonstrated its capability to overcoming the complexities of the process and deliver quality coatings. This paper aims at determining the durability and stability of the gun, slurry feeder and their components. A continuous 144-hour duration test was performed, and the plasma torch and slurry feed parameters and performances were recorded. The test results indicated that the equipment and process are stable and reliable, and ready for industrial application |
