Abstract

See full text

By utilizing the technique of this invention, parts such as gears, bearing races, and one-way clutches, which could previously only be made via labor intensive machining procedures can be made utilizing power metal technology. The subject invention provides a method of manufacturing a high strength part which comprised (1) providing an external component having an external profile and an internal profile, wherein the external component is comprised of a forged powder metal or a wrought metal; (2) compacting a powder metal composition within the internal profile of the external component to produce a green internal component having a desired internal profile; and (3) sintering the green internal component within the confines of the external component to produce high strength part, and wherein the internal component is comprised of a powder metal which expands to a greater degree than does the forged power metal or the wrought metal during sintering.
