Abstract: A flame spray device of the internal burner type has a fuel and oxidizer mixture combusted within a combustion chamber feeding products of combustion to a discharge nozzle passage of reduced inner diameter. An axially aligned metal piece injector has a centrally disposed injection bore hole positioned upstream of the combustion chamber and is provided with particles which are fed through the centrally disposed injection bore hole with the injection bore hole opening near the entrance of the nozzle passage. The metal piece terminates in a cone-shaped section with a reduced diameter end proximate to the entrance to the nozzle passage. A knife-edge terminal face is thereby produced intersecting the injector bore hole to minimize turbulence and rotation of the stream of carrier gas containing the powder exiting the injector metal piece injection hole. An annular jet stream surrounding the gaseous jet stream is wholly or partially formed of super-heated steam such that the steam, resulting from vaporization of water droplets, acts to cool the structural components of the internal burner. The device may alternatively be constituted by a plasma torch device.

Abstract: A method for forming an abradable composite material and the material so formed. A filler is fed axially into a stream of high-temperature combustion gases such that the filler is entrained in the gaseous stream. The gaseous stream containing the filler is then used to atomize the molten tip of a metal wire which is continuously fed into the gaseous stream. The resultant gaseous stream which contains both the filler and the atomized molten metal is directed to the surface of a target. The filler and the molten metal impact the target and combine to form a substantially continuous metal matrix in which the interstices are filled by the filler. The composite material abrades readily upon frictional contact with a moving part.

Abstract: Manufacture of glass mold plungers utilizes a thermal spray gun having combustion chamber with an open channel for propelling combustion products into the ambient atmosphere at supersonic velocity. The method comprises injecting into the chamber a combustible mixture of combustion gas and oxygen at a pressure in the chamber of at least two atmospheres above ambient atmospheric pressure, feeding into the chamber a powder comprising self-fluxing alloy particles, and combusting the combustible mixture in the chamber means whereby a supersonic spray stream containing the powder is propelled through the open channel. The spray stream is directed toward a glass mold plunger substrate such as to produce a coating thereon which is ground and polished. The coating may be fused prior to grinding.

Abstract: An attachment for supersonic thermal spray equipment by which inert shield gas is directed radially outwardly about the central core of a supersonic, particle-carrying flame to isolate the same from ambient atmosphere. The shield gas is injected tangentially against the inner surface of a constraining tube attached to and extending from the discharge end of the thermal spray gun nozzle, causing the shield gas to assume a helical flow path which persists until after it exits the tube and impacts the work piece. A process using the shielding apparatus with a high-velocity, thermal spray gun and employing oxygen and hydrogen as gases of combustion and inert gas to introduce metal powder, having a narrow particle size distribution and low oxygen content, into the high-velocity combustion gases, produces significantly improved, high-density, low-oxide metal coatings on a substrate.
