Abstract
Various aspects of the present disclosure relate to a nozzle insert which may be used with a thermal spray gun apparatus. A nozzle insert according to the disclosure may include a body having an outer surface, the outer surface of the body being configured to circumferentially contact and transfer heat to an inner face of a thermal spray gun nozzle of a thermal spray gun. The body of the nozzle insert may be removed from the thermal spray gun nozzle without disassembling the thermal spray gun, and includes an axial passage configured to communicate a plasma discharge from the nozzle insert. A thermal spray gun apparatus and a thermal spray gun system including the nozzle insert are also disclosed.
Claims13
A thermal spray gun system comprising:
- an electrode housing an electrode;
- a thermal spray gun body having a fore portion and an aft portion, the thermal spray gun body housing a thermal spray gun nozzle at the fore portion and coupled to the electrode body at the aft portion, the thermal spray gun nozzle having a discharge end, a body end, and a tapered interior face extending therebetween, wherein a cross-sectional area of the thermal spray gun nozzle at the discharge end is greater than a cross-sectional area of the thermal spray gun nozzle at the body end;
- and
- a removable nozzle insert in circumferential contact with the tapered interior face of the thermal spray gun nozzle and configured to transfer heat thereto, the removable nozzle insert including an axial passage configured to communicate a plasma discharge from within the thermal spray gun body;
- wherein the electrode body is configured to generate an electrical arc between the electrode and the thermal spray gun body, for converting a feedstock into the plasma discharge.
