摘要： In a thermal spray process, a wire (14) is fed into a flame-jet (20) to heat said wire (14) to the melting point, atomize and projected high velocity the droplets so formed against a surface (28) to buildup a coating of material (24) on the surface (28). The wire (14) is fed into the flame by aligning the cast-plane of the wire (14) with the flame-jet (20) by using a tubular member formed into a circular shape (30) to provide sufficient length to guide wire (14) and to provide the necessary twist amount to the wire (14) to align the cast-plane with the axis of the flame-jet (20).

摘要： A powder or wire thermal spray gun (10), useful for spraying a low oxide coating of oxidizable material, comprises a nozzle member (54) with a nozzle face, and a gas cap (14) extending from the nozzle member (54) and having an inwardly facing cylindrical wall (86) defining a combustion chamber (82) with an open end (88) for propelling combustion products into the ambient atmosphere at supersonic velocity and an opposite end bounded by the nozzle face (89). An annular flow of a combustible mixture is injected form the nozzle member (54) coaxially into the combustion chamber (82) at a pressure therein sufficient to propel combustion products of the mixture from the open end (88) at supersonic velocity. A first annular flow of inert gas is injected adjacent to the cylindrical wall (86) radially outward of the annular flow of the combustible mixture. Heat fusible thermal spray material is fed from the nozzle member (54) into the combustion chamber (82) radially inward of the combustible mixture, whereby a supersonic spray stream containing the heat fusible material in finely divided form is propelled through the open end (88). A second annular flow of combustion gas is directed adjacently surrounding the spray stream forwardly from the open end (88). A third annular flow of inert gas is directed adjacently surrounding the second annular flow forwardly of the open end (88).
