Claim 0:
1. A method of manufacturing a multi-metallic pressure-controlling component, comprising:
disposing a first metal alloy powder in a canister;
disposing a metal alloy boundary layer on top of the first metal alloy powder in the canister;
disposing a second metal alloy powder on top of the metal boundary layer 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, the metal boundary layer, and the second metal alloy powder to form the multi-metallic pressure-controlling component,
wherein the metal boundary layer 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 form 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.
