Attachment of powdered metal to powder forged or wrought materials

Abstract

This invention relates to a method for manufacturing a metal part which comprises attaching a powder forged or wrought outer raced ID splined plate to a powdered metal inner splined connection gear, wherein the outer raced ID splined plate incorporates a female ID profile on the race, wherein the inner splined connection gear contains a mail OD profile on the exterior of the part, and wherein the splined plate and the splined connection gear are attached together by (1) sinter brazing, (2) laser brazing, (3) laser welding, (4) sintering a mechanical joint, or (5) staking. In practicing this method a tight mechanical joint is formed between the splined plate and the splined connection gear which can be made of highly dissimilar materials, such as a wrought metal and a sintered powder metal.
