摘要:
A fixture for holding a part (11) while it is being spray coated at an elevated temperature by placing the part (11) between a base (19) and an upper insulation board (21). The space (17) therebetween forms an area (17) for positioning the part (11) to be sprayed. The cover (19) and board (21) are sized to retain heat in the part (11) at a steady predetermined temperature when the part (11) is being spray coated. When spray coated the part (11) is heated for sufficient time to uniformly bring the part (11) to temperature, followed by applying a spray to coat the part (11).
摘要:
A plasma spray gun (10) comprises a nozzle (14), an upstream powder injector (50A,B), and a downstream powder injector (54A,B). The upstream powder injector is disposed outside the nozzle and axially adjacent a nozzle outlet. The downstream powder injector is disposed axially downstream of the first upstream powder injector. The downstream powder injector is operative in a first coating mode, and the upstream powder injector is operative in a second coating mode.

An exemplary device (20) for spray applications includes a nozzle (22) configured to emit a first fluid stream (60) in a downstream direction away from the nozzle (22). At least one feed port (30A...30E) situated near the nozzle (22) introduces an agent into the first fluid stream (60) to be carried by the first fluid stream (60) in the downstream direction. At least one cleaning port (40A...40E) situated near the nozzle (22) emits a second fluid stream (64) in a generally upstream direction toward at least one of the nozzle (22) or the feed port (30A...30E).
