    Abstract: An apparatus and method for thermal spraying a metal coating on a substrate is accomplished with a modified pulsejet and optionally an ejector to assist in preventing oxidation. Metal such as Aluminum or Magnesium may be used. A pulsejet is first initiated by applying fuel, air, and a spark. Metal is inserted continuously in a high volume of metal into a combustion chamber of the pulsejet. The combustion is thereafter controlled resonantly at high frequency and the metal is heated to a molten state. The metal is then transported from the combustion chamber into a tailpipe of said pulsejet and is expelled therefrom at high velocity and deposited on a target substrate.

    Abstract: Method for performing a thermal spray process. Method includes heating and/or accelerating a gas to form an effluent gas stream, feeding a particulate-bearing carrier stream through an axial injection port into the effluent gas stream to form a mixed stream, in which the axial injection port includes a plurality of chevrons located at a distal end of said axial injection port, and impacting the mixed stream on a substrate to form a coating.
