Claim 6:
7. A method of manufacturing a multi-metallic pressure-controlling component, comprising:
disposing a first metal alloy powder in a canister;
disposing a metal alloy foil on top of the first metal alloy powder in the canister;
disposing a second metal alloy powder on top of the metal alloy foil in the canister;
sealing the canister; and
performing a hot isostatic pressure (HIP) process by applying heat and pressure to the canister to condense the first metal alloy powder and the second metal alloy powder to form the multi-metallic pressure-controlling component;
wherein the first metal alloy and the second metal alloy are independently selected from the group consisting of: chromium-molybdenum (Cr—Mo) steels, chromium-nickel-molybdenum (Cr—Ni—Mo) steels, maraging steels, super martensitic stainless steels, precipitation-hardened nickel alloys, precipitation-hardened martensitic steels, solution-annealed nickel alloys, tool steels, cobalt-bound tungsten-carbides, nickel-bound tungsten-carbides, nickel-cobalt (Ni—Co) alloys, and cobalt-chromium (Co—Cr) alloys,
wherein the metal alloy foil is positioned to enable the first metal alloy powder to form opposed exterior surfaces of a first section of the multi-metallic pressure-controlling component, to enable the second metal alloy powder to fill an interior in the first section between the opposed exterior surfaces of the multi-metallic pressure-controlling component, and to enable the second metal alloy powder to define an outer surface of a second section of the multi-metallic pressure-controlling component.
