Hopper

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&#x2014;which is less costly to manufacture and maintain.

Electrode

Interchangeable or standard electrode interface for a thermal spray plasma gun includes an interchangeable electrode having a first connecting section and a first annular coupling surface. A second connecting section is arranged in a plasma gun and includes a second annular coupling surface. An annular seal is spaced or axially spaced from an annular interface formed between the first and second annular coupling surfaces.

Plasma gun

Plume shield shroud () for a plasma gun () includes a substantially tubular member () comprising an axial length, a plume entry end (), and a plume exit end (). The shroud () is adapted to be mounted to a plasma gun (). A method of protecting, confining or shielding of a gas plume of a plasma gun () includes mounting () a gas plume shroud () on the plasma gun () such that the shroud () is sized and configured to substantially surround at least a portion of the gas plume.
