ABSTRACT:
A composite heavy-duty machine element such as a face gear (FIG. 7), a spur or helical gear (FIG. 14), or ball bearing races (FIG. 18), has its working or load bearing portion composed of sintered powdered high-performance alloy while its supporting portion not subjected to concentrated or intense heavy loads is made of a base metal such assintered powdered iron. In FIGS. 1 through 18 the powders of the two portions are inserted separately and successively in the die cavity of a briquetting press and simultaneously compacted to form a composite briquette which is then sintered to bond the separate portions together even though they are of different materials with different physical characteristics. The resulting composite sintered powdered metal machine element is of lower material cost than such an element formed of high-performance alloy in its entirety, and may then be used as it is if of satisfactory density for its intended use, or it may be further densified by means of an additional compressing operation with the article cold, warm or by a hot forging operation, or with subsequent sintering if deemed necessary depending upon its intended use. If the machine element is to be a face gear, the face gear as briquetted and sintered is subjected to a further deforming operation to so incline its teeth.
