Abstract
A thermal spray gun having an advanced, streamlined design which simplifies assembly of the gun components and reduces maintenance downtime. The thermal spray gun has a fuel/oxidant gas nozzle with a plurality of oxygen outlets arranged in a ring upon a discharge face. Three alternative fuel gas outlet configurations provide a combustion flame within a barrel having an inlet adjacent the fuel/oxidant gas nozzle discharge face. Powdered feedstock is supplied through a centrally disposed feedstock injector and is heated by the combustion flame. Oxidant gas, fuel gas and power feedstock are simultaneously discharged into the barrel, through a single plane perpendicular to the direction of gas and feedstock flow.
