Abstract
A part includes a three-dimensional porous metallic workpiece printed via an additive manufacturing process and subsequently subjected to a diffusion-based process to convert at least a portion of the porous metallic workpiece to a ceramic workpiece or an intermetallic workpiece.
Claims12
A method of manufacturing a part, comprising:
- printing a three-dimensional porous metallic workpiece via an additive manufacturing process;
- and
- subjecting the porous metallic workpiece to a diffusion-based process and thereby converting at least a portion of the porous metallic workpiece to a ceramic workpiece or an intermetallic workpiece,
- wherein the porous metallic workpiece comprises a metal or a metal alloy that forms one of a carbide, a nitride, a boride, an oxide, a silicide, or an intermetallic upon being subjected to a reaction atmosphere of the diffusion-based process.

A method of fabricating a drill bit, comprising:
- positioning one or more ceramic or intermetallic workpieces into a mold assembly that defines at least a portion of an infiltration chamber, wherein each ceramic or intermetallic workpiece is made by:
- printing a three-dimensional porous metallic workpiece via an additive manufacturing process;
- and
- subjecting the porous metallic workpiece to a diffusion-based process and thereby converting at least a portion of the porous metallic workpiece to a ceramic workpiece or an intermetallic workpiece, wherein the porous metallic workpiece comprises a metal or a metal alloy that forms one of a carbide, a nitride, a boride, an oxide, a silicide, or an intermetallic upon being subjected to a reaction atmosphere of the diffusion-based process;
- depositing reinforcing materials into the infiltration chamber;
- and
- infiltrating the one or more ceramic or intermetallic workpieces and the reinforcing materials with a binder material and thereby producing a composite.
