Laminated composite of magnetic alloy powder and ceramic powder and process for making same
First Claim
1. A method for manufacturing a laminated composite structure, comprising the steps of:
- assembling in a cavity alternating layers of uncoated metal powder particles and an inorganic bonding media, said inorganic bonding media selected from at least one of the group of powders consisting of a ceramic, glass, and glass-ceramic; and
,applying heat to said alternating layers until the particles of each said layer of said metal powder are sintered together, each said layer of said inorganic bonding media is sintered, and said alternating sintered layers are bonded to one another to form a strong laminated composite structure.

Abstract
A laminated composite structure of alternating metal powder layers, and layers formed of an inorganic bonding media powder, and a method for manufacturing same are discosed. The method includes the steps of assembling in a cavity alternating layers of a metal powder and an inorganic bonding media of a ceramic, glass, and glass-ceramic. Heat, with or without pressure, is applied to the alternating layers until the particles of the metal powder are sintered together and bonded into the laminated composite structure by the layers of sintered inorganic bonding media to form a strong composite structure. The method finds particular application in the manufacture of high performance magnets wherein the metal powder is a magnetic alloy powder.
