Thermal spray gun () and/or nozzle () includes a nozzle body and a liner material () arranged within the nozzle body. A material of the nozzle body has a lower melting temperature than that of the liner material (). A wall thickness (C) of the liner material () has a value determined in relation to or that corresponds to a wall thickness (D) of the nozzle body. Alternatively or additionally, a ratio of a total wall thickness of a portion of a nozzle () to that of a wall thickness (C) of the liner material () has a value determined in relation to or that corresponds to the wall thickness (C) of liner material ().

Method and apparatus for monitoring and diagnosing gun performance is derived that can determine proper gun operation and if not operating properly diagnose potential causes for abhorrent operation. The voltage produced by the gun is sampled in real time and the frequency spectrum produced analyzed using FFT and then reducing the FFT pattern down to a set of numerical values or a signature that can be compared to known signatures for both correct operation and abnormal operation. Using best fit techniques the cause of any abnormal behavior can then be identified. The method can also be used to predict the end of hardware life and aid in production scheduling and spare parts acquisition by providing advanced notice of wear and usage.

Plasma gun diagnostics using real time voltage monitoring

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.

A plasma nozzle () having a nozzle body and a liner material () arranged within the nozzle body. The liner material () has a higher melting temperature than the nozzle body and includes one of a Tungsten alloy having a cross-sectional thickness (C) significantly greater than 0.25 mm, Molybdenum, Silver and Iridium.

Long-life plasma nozzle with liner

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.
