摘要:
A method of forming a wear-resistant coating on a surface of a substrate includes the step of depositing a material comprising a rhenium-based composition onto the substrate surface using a handheld laser deposition device. A soluble interlayer may be formed on the surface of the substrate prior to the laser deposition step, and a heat treatment may be performed after the laser deposition step.

There is provided a method for repair of a regulator valve. The present invention provides a method for repairing a regulator valve. The method provides a machining of a housing so as to incorporate an oversize poppet. A poppet is provided that matches the resized housing. Further the poppet is shaped so as to provide an increased efficiency in the regulation of the air flow through the valve. Additionally the poppet is selected of a material that provides an increased wear life over the original material.

Embodiments of a lightweight, high temperature airborne valve are provided. In one embodiment, the airborne vale includes a valve element and a flowbody. The flowbody is formed at least partially from a titanium aluminide alloy and has a flow passage therethrough in which the valve element is movably mounted. Embodiments of a method for producing such a lightweight, high temperature airborne valve are also provided. In one embodiment, the method includes the steps of forming a lightweight flowbody at least partially from a titanium aluminide alloy, hot isostatically pressing the lightweight flowbody, and machining the lightweight flowbody to desired dimensions.

Methods of manufacturing a noise attenuator are provided. In an embodiment, by way of example only, the method includes shaping a plate to have a three-dimensional contour, and forming a plurality of openings through the shaped plate with an abrasive fluid jet to thereby form the bleed valve noise attenuator. In another embodiment, a bleed valve assembly is provided. By way of example only, the assembly includes a plate having a three-dimensional contour including a rim section surrounding a dome section and a plurality of openings formed in at least one of the rim section and the dome section, the plate comprising a material having no recast material thereon.

A method is provided for manufacturing a magnetic steel component. An electroless nickel plating is formed on a substrate that includes magnetic steel. A thermal cycle is thereafter performed at a temperature that is sufficiently high to sinter the electroless nickel plating and thereby form a densified plating on the substrate. According to one embodiment, the thermal cycle includes a solid state diffusion sintering process wherein the substrate and the densified plating are heated to a temperature of at least about 1300° F. (about 704° C.) but.below the melting temperature of the electroless nickel plating. According to another embodiment, the thermal cycle includes a transient liquid phase sintering process wherein the substrate and the densified plating are heated at least to the melting temperature of the electroless plating.
