Abstract

A method of processing a bimetallic part includes depositing an intermediary material having a metal powder onto a tooling surface of a cavity of a tool, transforming the intermediary material into a metal layer having a first composition on the tooling surface, and forming a metal core having a second, different composition in the cavity such that the metal layer bonds to the metal core to form a bimetallic part.

Claims (5)

1. A method of processing a bimetallic part, comprising:

depositing an intermediary material having a metal powder onto a tooling surface of a cavity of a tool, wherein the intermediary material is slurry having the metal powder and a binder selected from the group consisting of polysaccharide, sugar, glycine, proline, hydroxyproline and amino acids;

transforming the intermediary material into a metal layer of a first composition on the tooling surface; and

forming a metal core of a second, different composition in the cavity such that the metal layer bonds to the metal core to form a bimetallic part,

wherein the tooling surface is contoured and non-segmented with respect to bonded seams in the tool.
