Method of manufacturing net-shaped bimetallic parts

摘要

A method for manufacturing a net-shaped bimetallic part that includes the steps of: providing a tool that defines a cavity and a tooling surface; depositing a layer of an environmental metal material onto the tooling surface; filling the cavity in the tool with a powdered metal material; and simultaneously heating the tool and subjecting the tool to a pressurized gas to consolidate the powdered metal material and diffusion bond the environmental metal material to the consolidated powdered metal material to form a bimetallic part.
