ABSTRACT:
A high velocity, oxygen fuel ("HVOF") thermal spray gun for spraying a melted powder composition of, for example, thermoplastic componds, thermoplastic/metallic composites, or thermoplastic/ceramic composites onto a substrate to form a coating thereon. The gun includes an HVOF flame generator for providing an HVOF gas stream to a fluid cooled nozzle. A portion of the gas stream is diverted for preheating the powder, with the preheated powder being injected into the main gas stream at a downstream location within the nozzle. Forced air and vacuum sources are provided in a shroud circumscribing the nozzle for cooling the melted powder in flight before deposition onto the substrate.
