摘要： The invention provides an accurate powder metal component having a body with opposed surfaces at least one of which has at least one projection of smaller cross-sectional area than the main portion of the body of the component. The distance from the free end of the projection to the opposite end of the component defines one dimension of the component that must be relatively accurate, in one embodiment to slide against and form a seal that inhibits liquid flow against another component of an assembly. In the manufacturing method, the powdered metal component is made by compaction to form the body including a projection at the end, is sintered and thereafter is reduced in the dimension between the end of the projection and the opposite end of the component by coining the free end of the projection so as to reduce the dimension to within a tolerance of the nominal specified dimension.

摘要： Disclosed is a sintered gear composed of a sintered alloy having a metal matrix and pores. The tooth surface (2, 3, 4) of the tooth and the bottom land (5) have a densified layer (11) in which the porosity is reduced to 10% or less from the sintered alloy. The densified layer at the tooth surface is formed with a thickness of 300 to 1,000 microns, and the densified layer at the bottom land is formed with a thickness of 10 to 300 microns. The boundary surface of the densified layer is continuous from the tooth surface side to the bottom land side so as not to have a substantial level difference.

摘要： A method of flow forming sintered metal parts. The first step is forming a round disk by conventional powder metal process. The disk can be a donut shape part with or without a flange on one side of its outer diameter. The disk can then be copper impregnated or used as is, depending on the requirements. The disk is placed in a spinner held in proper tooling and grooves are spun in its outer diameter. The spinning can be done with a finishing roller or by a pre-finishing roller, followed by a finishing roller. This process not only creates a part with great accuracy, it also densifies and eliminates the powder metal porosities on the surface layer by the pressures inserted in spinning.
