20130284203 | PLASMA SPRAY APPARATUS INTEGRATING WATER CLEANING - An integrated apparatus and method comprises a plasma gun with a water supply, treatment fluid supply, and controls, the combination of which is adapted for directing a plume onto a surface of a three-dimensional part to treat the surface; and for controlling injection of water into the plume with the plume directed onto an adjacent surface to clean debris and undesired material from the adjacent surface; and for subsequently directing the plume (without water) onto the adjacent surface to treat the adjacent surface. The apparatus and method are particularly useful in suspension plasma spray systems, but are not believed to be limited to that. | 10-31-2013 |
