    摘要: An improved thermal spray apparatus and method of promotes mixing of axially fed particles in a carrier stream with a heated effluent stream without introducing significant turbulence into either the effluent or carrier streams. An axial injection port includes a plurality of chevrons at the distal end of the port. The chevrons are located radially around the circumference of the distal end of the axial injection port to increase the shared area between the two flow streams at the outlet of the port.

    摘要: A two stage kinetic energy spray device has a first stage first nozzle having a receiving end that receives a particulate stream, an injection end located axially to the first nozzle receiving end, the injection end receiving the particulate stream from the receiving end. A second stage has a second nozzle, the second nozzle having a gas receiving portion that receives an effluent gas, a convergent portion that is downstream from the gas receiving portion and a divergent portion that is downstream from the convergent portion, the convergent portion and the divergent portion meeting at a throat. The particle stream is accelerated to a first velocity in the first nozzle located within the second nozzle divergent portion The effluent gas is accelerated to a second velocity in the second nozzle. First nozzle injection end chevrons allow mixing of particulate and supersonic effluent streams prior to exiting the spray device.

    摘要: Water cooling system (1) for a plasma gun (2), method for cooling a plasma gun (2) and method for increasing a service life of a plasma gun (2). The system (1) includes a water cooler structured and arranged to remove heat from cooling water to be supplied to the plasma gun (2), a controller (7) structured and arranged to monitor a gun voltage of the plasma gun (2), and at least one flow valve (8) coupled to and under control of the controller (7) to adjust a flow of the cooling water. When the gun voltage drops below a predetermined value, the controller (7) controls the at least one flow valve (8) to increase the plasma gun temperature and the gun voltage.

    摘要: Shaping the feed wire for a combustion wire thermal spray process improves the operating capability of the combustion wire gun through higher feed rates and high operating efficiencies. The efficiency of the wire melting is increased over conventional systems through increasing the surface area of the wire cross section and exposing more of the wire material directly to the burner jets.

    摘要: An apparatus for and a method of prepping a surface of a cylinder bore using a pulsed waterjet entails generating a signal having a frequency f using a signal generator, applying the signal to generate a pulsed waterjet through an exit orifice of a nozzle having an exit orifice diameter d and a length L. The pulsed waterjet prepares the surface to within a predetermined range of surface roughness. The surface roughness is determined by selecting operating parameters comprising a standoff distance (SD), a traverse velocity VTR of the nozzle, a water pressure P, a water flow rate Q, a length-to-diameter (L/d) ratio, the frequency f, and an amplitude A of the signal.
