摘要:
A hopper assembly includes a hopper configured to contain a feedstock material. A vibration imparting device is arranged inside the hopper and a vibration source coupled to the vibration imparting device. Embodiments of the instant invention are believed to provide various improvements in feeding uniformity by providing various hopper configurations that ensure a more consistently uniform filling of the metering device for a variety of difficult-to-feed materials and not-so-difficult-to-feed materials. One, more or all of these embodiments are also believed to improve accuracy and add precision to control, and, in addition, offer more simplified hopper construction—which is less costly to manufacture and maintain.

Nozzle for thermal spray gun, thermal spray gun and method for forming nozzle. Nozzle includes a nozzle body having a central bore and an exterior surface structured for insertion into a thermal spray gun and a water coolable surface coating applied onto at least a portion of the exterior surface. The water coolable surface coating is structured to protect the exterior surface from a chemical interaction with cooling water guided through the thermal spray gun.
