    摘要： An environmentally resistant gas turbine engine disk is disclosed. The disk includes a substrate metal having locally enriched surface regions, the locally enriched surface regions comprising alloying elements present in a higher percentage than found in the substrate metal. A method for making the disk and other articles is also disclosed. The method includes furnishing a plurality of powder particle substrates made of a substrate metal, providing a nonmetallic precursor of a metallic coating material, wherein the metallic coating material includes an alloying element that is thermophysically melt incompatible with the substrate metal, contacting the powder particle substrates with the nonmetallic precursor, and chemically reducing the nonmetallic precursor to form coated powder particles comprising the powder particle substrates having a surface-enriched layer of the metallic coating material thereon, wherein the step of chemically reducing is performed without melting the powder particle substrates.

    摘要： An apparatus for producing a molten metal flow comprises a refining hearth having a water-cooled wall, and an entry flow channel through the wall of the hearth disposed tangentially to the wall such that a flow of molten metal introduced into the hearth through the entry flow channel flows tangentially to the wall of the hearth. The hearth further has an exit flow channel through the wall of the hearth disposed tangentially to the wall. The molten metal entering the refining hearth flows in a vortex pattern, aiding in the removal of solid particulate matter from the metal. The refining hearth may be agitated by an induction coil placed adjacent to the hearth. The exit flow may be through a number of adjacent exit flow channels to reduce its local velocity.

    摘要： An apparatus that controls the flow of a stream of metal, such as produced from the bottom of a hearth, includes a cylindrical metallic nozzle body having a hollow wall which includes a slit extending substantially parallel to the axis of the cylinder so that there is no electrical continuity around the nozzle wall across the slit. The walls of the cylinder are preferably formed of hollow tubes through which cooling water is passed. A sensor senses a performance characteristic of the apparatus, such as the temperature of the nozzle body. An induction heating coil surrounds the nozzle body, and a controllable induction heating power supply is connected to the induction heating coil to provide power. A controller controls the power provided to the induction heating coil by the induction heating power supply responsive to an output signal of the sensor, so that a selected performance characteristic of the apparatus may be maintained.

    摘要： A method for atomizing high temperature melts to achieve greater efficiency and smaller particle size is described. The method involves the employment of lower pressure gas coupled with an atomization nozzle larger than prior art structures. The atomization nozzle is part of a close coupled atomization structure having shallow depth dimension. The method allows atomization at melts with reduced likelihood of freeze off. The method reduces heat extraction from the melt while the melt is still contained in the atomization nozzle.

    摘要： Apparatus for producing a metal powder includes a cooled hearth structure in which a metallic alloy is melted and a heat source above the hearth positioned to heat the melt in the hearth. The cooling of the hearth causes a protective hearth skull to form between the melt and the hearth itself. The hearth is placed within an environmental control chamber. A supply structure provides a continuous supply of the metallic alloy to the hearth structure from the exterior of the chamber. A metal powder producer is positioned to receive molten metal from the hearth, and a continuous stream of the molten alloy from the hearth is transferred to the metal powder producer. The transfer is accomplished by tipping the hearth or by teeming through an opening in the bottom of the hearth. The hearth structure can utilize two individual hearths, controllably arranged so that molten metal is drawn from one hearth while the other is recharged.

    摘要： A process and apparatus for producing a spray of atomized metal droplets includes providing an apparatus that forms a spray of molten metal droplets, the apparatus including a metal source and a metal stream atomizer, producing a stream of liquid metal from the metal source, and atomizing the stream of liquid metal with the metal stream atomizer to form the spray of molten metal droplets. A controlled spray of atomized metal droplets is achieved by selectively varying the temperature of the droplets in the spray of molten metal droplets, the step of selectively varying including the step of varying the flow rate of metal produced by the metal source, responsive to a command signal, and sensing the operation of the apparatus and generating the command signal indicative of the operation of the apparatus. The step of atomizing may be accomplished by directing a flow of an atomizing gas at the stream of liquid metal, and then selectively controlling the flow rate of the atomizing gas.
