    Abstract: 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.

    Abstract: Provided is a resin coated member produced according to a coating method through HVOF spraying that comprises generating a combustion jet in a combustion chamber connected to one end of a barrel while controlling the temperature of the combustion jet by supply of an inert gas to the jet, feeding resin coating materials into the temperature-controlled combustion jet and leading them to pass through the barrel, and spouting the coating particles through a spout port along with the combustion jet therethrough to thereby coat the substrate surface; wherein the length of the barrel, the temperature of the combustion jet and the physical properties of the coating particles are defined so as to satisfy both the following formulae (1) and (2), and wherein the interface between the coating material and the substrate surface has a structure of such that the two break in each other with at least micron-pitch irregularities.
