Abstract
A plasma spray gun system with improved nozzle life. The gun includes a nozzle with a thin annular coolant passage and having a dimension optimized for nozzle life. The system also includes a deionizer to remove ions from the cooling fluid and a dissolved gas remover which also improves nozzle life. In addition, the coolant is treated to remove ions which extends nozzle life even more. Further cooling fluid treatment for even further nozzle life includes dissolved gas removal and heat removal.
