    摘要： A method of producing a metallic composite component or a blade for a gas turbine engine includes: providing a core of a ceramic or metallic foam material; disposing the core in a mold having a cavity defining the exterior contour of the component or blade includes; injecting the mixture into the mold so as to penetrate the intracellular volume of the foam; removing a majority of the binder from the preform; and heating the preform to remove the remainder of the binder and sinter the metal powder together to form the finished component or blade. A preform for a metallic composite component includes a core of a foam material having ceramic or metallic cell walls with intracellular volume therebetween. The core defines at least a portion of the exterior contour of the component. A mixture of a metallic powder and a binder is disposed in the intracellular volume.

    摘要： A heat treatment process that will restore the mechanical properties of an aircraft engine article that includes a cast nickel-based superalloy portion welded to a wrought portion. The heat treatment process includes placing an article that includes the nickel-based superalloy cast portion into a heat treatment chamber, evacuating the chamber to a suitable atmosphere, heating the chamber in a manner that minimizes distortion of the cast portion to a temperature in the range of 1950° F. to 2050° F., holding the temperature in that range for a period of time sufficient to solution all the delta phase precipitates, and then cooling the article to room temperature in a manner that minimizes distortion of the article. After solution heat treatment, the wrought portion of the engine part can be removed and replaced and the engine article can be reprocessed.

    摘要： A restored or regenerated article including a residual substrate comprised of a first material and a restorative or regenerative layer of second material overlying at least a portion of the residual substrate. The second material is substantially similar in composition to the first material to promote an integral bond therebetween. The second material comprises the deposit of a suitable deposition process, i.e., vapor phase deposition, cathodic arc deposition, or sputtering. The restored/regenerated article includes an environmental coating at least partly diffused into the restorative or regenerative layer. The environmental coating comprises a deposit from a deposition process selected from vapor phase deposition, cathodic arc deposition, and combinations thereof. Heat treatments of about 2 hours or longer at temperatures between about 1500 ° F. to about 2300° F. (about 816° C. to about 1260° C.) to enhance the bond between the residual substrate and the restorative/regenerative layer. Surface characteristics of the restored/regenerated component may be enhanced by a suitable surface treatment such as grit blast polishing.
