    Abstract: A method of fabricating a foamed metal structure using a powder supply of metal particles, comprising: (a) introducing the powder supply along with foaming agent particles into a propellant gas to form a gas/particle mixture stream; (b) projecting the mixture stream at a critical velocity of at least sonic velocity onto a metallic substrate to create a deposit of pressure-welded metal particles containing the admixed foaming agent; and (c) subjecting at least the coating of the substrate to a thermal excursion effective to activate expansion of the foaming agent while softening the metal particles for plastic deformation under the influence of the expanding gases.

    Abstract: A method of manufacturing a metal and polymeric composite article by the following steps. Droplets of spray deposited metal and spray deposited polymeric material are combined to form an article having the polymeric material interspersed within the metal. A carrier or form that shaped to receive the metal and polymeric layers is provided. The carrier may be made either stationary or movable. Layers of spray deposited metal and spray deposited polymeric material are applied atop the carrier. The spray deposited metal is between 90 and 95 percent by volume of the article. The polymeric layers do not completely cover the metal layers. Succeeding spray deposited metal layers contact bond to previous metal layers. The polymeric material between imbedded between the interconnected metal layers.

    Abstract: A machine tool or die that is fabricated from thermally spray-formed steel is easily repaired by cleaning, roughing and covering the surface to be repaired by a cold-spray layer of metal and then forming a weldment by conventional electric welding processes. The repaired surface is then finished by conventional machining, grinding and polishing and then the tool is put back into service.

    Abstract: A method of making valve guides by thermal spraying a wear-resistant layer onto a rotating mandrel that is subsequently built up by thermal spraying steel on the wear-resistant layer. A flame spray polymer lubricant may be applied to the wear-resistant layer to improve self-lubricating properties of the engine valve guide. The mandrel and applied layers are then cut off and the remaining segment is further processed in a machining operation to remove the mandrel from the inside of the engine valve guide. The mandrel is preferably cooled as the thermal spray is applied preferably by routing a cooling fluid such as air through the mandrel.

    Abstract: Transmission torque converter reactor thrust washer segments (12) comprising a surface hardenable aluminum alloy are subjected to electrical discharge machining (EDM) using an electrode (26) and under conditions effective to impart a hydrodynamic bearing surface profile to the segment surfaces (12a), reduce segment surface roughness, and increase segment surface hardness. Torque converter reactors (10) having integrated thrust washer segments machined in this manner exhibit improved wear resistance and hydrodynamic lift when compared to as cast thrust washer segments.

    Abstract: A method of defining valve seats on valve seat supports of an internal combustion engine head. The method includes steps of; (a) roughening the exposed surface of the valve seat support to a finish of 10-50 .mu.m RA; (b) thermally spraying a stream of composite particles onto the roughened support surface, using gaseous propellants with sufficient heat and force to produce a dense adherent composite coating of metal and metal oxide particles and to a thickness no greater than 1-1.5 mm; and (c) finish machining if necessary, the sprayed coating to define the valve seat surface. The composite coated product consists of a metal/metal oxide mixture that possesses one or more of the following characteristics: a surface porosity of 2-5%, a density of 6.5-8 grams/cc, a Vickers hardness of about 280 kg/mm.sup.2 at 450.degree. C., high wear resistance and high corrosion resistance.
