Abstract: A high velocity gaseous jet stream which may be a cold jet stream of compressed air or a jet flame discharging from an internal burner discharges through an open slot V-shaped, U-shaped or C-shaped, or alternatively through separate circumferentially spaced parallel passages to form a volumetric zone of quiescent gas well into the main jet prior to downstream folding of the quiescent zone to form a single symmetrical jet stream, thereby permitting abrasive particles for sandblasting, a solid material particles which are subsequently melted or at least heat-softened prior to impact on a substrate for spray coating. As such the gaseous accelerating medium does not interference with the introduction of the particle or the solid rod from which the particles separate after melting to the center of the accelerating stream, thereby maintaining concentricity of the gas stream about the particles facilitating the focusing of the particle stream and maximizing acceleration effect to the particles so introduced.

Abstract: A method for producing a porous boiling surface with exceptional adhesion qualities and mechanical strength while at the same time maintaining the high degree of open cell porosity required for effective boiling heat transfer wherein a bond coating of pure aluminum is produced using a thermospray gun to melt an aluminum wire and impinge the molten aluminum particles against the metallic substrate in an inert gas stream projected from the gun nozzle located between 2 and 4 inches from the substrate. The bond coating has a porosity of less than 15 percent and a thickness not greater than 4 mils. The nozzle to substrate distance is then increased to 4 to 10 inches and a top coating of pure aluminum is formed having a porosity greater than 18 percent and a thickness of at least four times the thickness of the bond coating.

Abstract: A method for repairing turbine vanes and the like which have become worn or cracked after extended periods of use. The method embraces the steps of applying molten metal containing a predetermined quantity of silicon to the cracks, and overall to the worn or eroded areas of the vane to build up the same beyond its original surface, sintering the vane in a furnace at a temperature of over 2,000.degree. F thereby burning off some of the silicon, allowing the vane to cool, and thereafter placing it in a high pressure furnace and subjecting it simultaneously to heating to a temperature in excess of 2,000.degree. F and a pressure in excess of 15,000 PSI to drive the build-up material into all of the cracks of the vane and simultaneously effect a densification of the material as well as improving the bond to the original eroded surfaces. Thereafter the vane is removed and allowed to cool, and the built-up surface of the vane is ground down so as to restore the dimensions of the piece substantially to those of a new part.

Abstract: A method for coating a cylindrical container with a thin, resinous coating by spraying powdered resin is disclosed. The technique involves spraying of finely divided resin particles at a velocity of at least about 200 feet per minute from a spray nozzle external to the container into the interior of a rapidly revolving container, particularly slender, cylindrical containers. The container may be sprayed by directing a pulse of a predetermined quantum of resin into the container to deposit a substantially uniform coating. Alternatively, a continuous flow of resin at a predetermined rate may be sprayed into a container. The resin particles are caused to adhere to the container by preheating the container. The coating is rendered continuous by preheating the container to temperatures above the softening point of the resin. Postheating of the coated container at temperatures in excess of about 300.degree. F matures the coating.

Abstract: A new ceramic treatment process and product and, more particularly, a process for forming and treating and shaping and treating of porous skeletal bodies to produce hardened dimensionally stable end products of relatively low temperatures and the resulting materials produced thereby which comprises the steps of treating a porous skeletal body by impregnating the interstices of the porous body with a compound of a metal capable of being converted to an oxide in situ at relatively low temperatures, heating the body so impregnated at temperatures well below normal vitrification to a temperature of at least 600.degree.F. and for a period of time sufficient to convert the compound impregnated therein to an oxide and repeating the impregnation and heating steps until the desired degree of hardness is obtained. The invention further contemplates the forming of the porous body from relatively finely divided materials which may be relatively pure powders, mixtures of powders or impure powders, including additives in the form of discrete particles, fibers, fillers and the like, which powders are molded and bound together or bound together and molded with a binder which may comprise the impregnating compound or other suitable binder prior to treatment.

Abstract: A method of protecting the surface of a moulded plastic part made from synthetic resin, fillers and/or fibers by application of a protective film of ceramic, metallic, or metallic-ceramic composition which is sprayed onto the surface of the parent material wherein the adhesion between the parent material and the sprayed-on protective film is improved by application of an intermediate stratum, in the form of a fabric or other mesh-like material made from an organic or inorganic substance, to the surface of the parent material prior to the spraying step. The mesh-like material is resistant to temperatures higher than the curing temperature of the synthetic resin and may be applied either simultaneously with production of the moulded plastic part and afterwards by means of adhesives.
