  • Physical property improvement of iron castings using carbon nanomaterials
    Patent number: 10844446
    Abstract: A method is provided for fabricating iron castings for metallic components. The method for fabricating the iron castings may include forming a molten solution by melting carbon and iron and combining carbon nanomaterials with the molten solution. A first portion of the carbon nanomaterials combined with the molten solution may be dispersed therein. The method may also include cooling the molten solution to solidify at least a portion of the carbon thereof to fabricate the iron castings. The first portion of the carbon nanomaterials may be dispersed in the iron castings.
    Type: Grant

  • ONE-PIECE MANUFACTURING PROCESS
    Publication number: 20140230247
    Abstract: A method of making a turbomachine part, wherein the method can include machining a blank into a base having blades extending therefrom, the blades defining a channel therebetween. The method can also include forming a bridge constructed from refractory material in the channel between the blades, and forming a cover on the tops of the blades and over the channel, such that the base, the blades, and the cover form a single substantially homogenous turbomachine part once the bridge is removed.
