摘要： A plasma arc torch that includes a torch body having a nozzle mounted relative to a composite electrode in the body to define a plasma chamber. The torch body includes a plasma flow path for directing a plasma gas to the plasma chamber in which a plasma arc is formed. The nozzle includes a hollow, body portion and a substantially solid, head portion defining an exit orifice. The composite electrode can be made of a metallic material (e.g., silver) with high thermal conductivity in the forward portion electrode body adjacent the emitting surface, and the aft portion of the electrode body is made of a second low cost, metallic material with good thermal and electrical conductivity. This composite electrode configuration produces an electrode with reduced electrode wear or pitting comparable to a silver electrode, for a price comparable to that of a copper electrode.

摘要： A coolant tube and electrode are adapted to mate with each other to align the tube relative to the electrode during operation of the torch. Improved alignment ensures an adequate flow of coolant along an interior surface of the electrode. In one aspect, an elongated body of the coolant tube has a surface adapted to mate with the electrode. In another aspect, an elongated body of the electrode has a surface adapted to mate with the coolant tube. The surfaces of the tube and electrode may, for example, be flanges, tapered surfaces, contours, or steps.

摘要： A plasma transferred wire arc thermal spray apparatus and method producing an extended-arc and supersonic plasma jet stream for applying a dense metallic coating on a substrate, such as a concave internal surface of a bore. The apparatus includes a plasma generating torch assembling having a cathode and an anode nozzle surrounding the cathode and a wire feeder which continuously feeds the tip of a wire feedstock opposite a constricted nozzle orifice and wherein the wire feedstock is maintained at the same positive electrical potential as the nozzle. Plasma gas is directed into the nozzle, preferably generating a vortex flow around the cathode and exiting the restricted nozzle orifice. The improved apparatus includes a pilot power supply and a high voltage or high frequency power supply which initiates the electric arc and the constricted plasma arc and a separate main power supply which extends the constricted plasma arc to the wire tip. In the disclosed bore coating apparatus and method, the plasma torch assembly is rotated about the longitudinal axis of the wire feedstock while maintaining the electrical connection between the wire feedstock and the nozzle. The apparatus further includes an annular conical port surrounding the restricted nozzle orifice connected to a second gas source which generates an annular conical gas stream surrounding the wire tip having a point of intersection spaced downstream of the wire tip and the second gas is further directed to the wire feed guide to cool the assembly.
