摘要： A method of carburizing a powder metal part involving more than one carburizing step. In a pre-forging carburizing step, a powder metal part that is less than fully dense is carburized to establish a pre-forging carburization profile. After the pre-forging carburizing step, the powder metal part is forged so that the powder metal part is increased in density and the pre-forging carburization profile is transformed into an as-forged carburization profile. In a post-forging carburizing step following the forging step, the powder metal part is again carburized, thereby resulting in both further diffusion of carbon from the as-forged carburization profile into the powder metal part and further introduction of carbon into the powder metal part at a surface of the powder metal part.

摘要： A method of sinter fitting a powder metal compact around a core forms a composite component. By exploiting the shrinkage associated with the sintering of a powder metal compact, a sintered powder metal section may be dimensionally shrunk onto a core to create a mechanical interference fit between a core section and a sintered powder metal section. This method may be used to join materials such as aluminum and steel together, which traditionally have been difficult to join to one another.

摘要： An improved planetary gear carrier assembly is disclosed including a carrier and a ring. The carrier has a hub extending in an axial direction. The hub has splines on a radially-outward facing surface that extend in an axial direction and further has a first set of groove sections on the radially-outward facing surface in which the first set of groove sections extends circumferentially around the hub and through the splines. The ring is received around the hub of the carrier and has splines on a radially-inward facing surface. The splines in the ring are received in the first set of groove sections by axially nesting the splines of the carrier and ring into one another and then angularly rotating the ring relative to the carrier. With the splines of the ring twisted in the groove sections of the carrier, the ring can be axially restricted relative to the carrier.

摘要： A method of manufacturing a machining tool in which an insert holder comprises a first surface, a second surface opposite the first surface, and a first insert tip slot extending between the first surface and the second surface. The first insert tip slot is configured so as to be compressed and densified to support a first insert tip. The insert holder further includes elevated projections extending from the first and second surfaces proximate the first insert tip slot.

摘要： A forged composite powder metal part, such as a CVJ inner race or bevel gear, and method of making the same are disclosed. The forged composite powder metal part includes a outer section concentrated with a first powder metal material, a inner section concentrated with a second powder metal material and a variable boundary profile between the materials of the two sections. For example, in a forged CVJ inner race, the different materials can provide improved wear resistance in the ball tracks and improved spline performance. As another example, in a forged bevel gear, the different materials can be used to create a continuous variable boundary profile that defines the depth of a harder layer over the teeth.

摘要： A component (10) is adapted for contact with a mating component (50) during attachment of the components to one another to form a related assembly in which a deformable pad (26) or pads improve stress distribution. The component includes a body having an interface surface in which the body is adapted to be contacted with the mating component at the interface surface of the body. One or more deformable pads are formed in the interface surface. Each deformable pad has a top surface that is offset outwardly from the interface surface relative to the body and a groove surrounding the deformable pad that is offset inwardly from the interface surface relative to the body.

摘要： A zirconium-doped aluminum powder metal and a method of making this powder metal are disclosed. The method of making includes forming an aluminum—zirconium melt in which a zirconium content of the aluminum—zirconium melt is less than 2.0 percent by weight. The aluminum—zirconium melt then powderized to form a zirconium-doped aluminum powder metal. The powderization may occur by, for example, air atomization.

摘要： A brazed part includes two or more components that are brazed together and has related method of making. Using a method of locating parts relative to one another, an inter-component gap between the components may be formed. Subsequently, during brazing, flow control features formed along the inter-component gap may then be used to assist in the retention of the braze material between the components during brazing.
