The invention relates to a method for producing a composite component (). At least one shaft () and at least one sintered part (), preferably in the form of a rotor or a cam, are assembled into the composite component. In order to assemble the composite component, at least the following steps are carried out: &#x2014;introducing the shaft () into a continuous bore () of the sintered part () and &#x2014;calibrating the sintered part () at least by means of a calibrating die (), furthermore preferably with the simultaneous application of an axial force onto the sintered part () by means of at least one upper punch () and at least one lower punch (), wherein the shaft () can be found in the bore () of the sintered part () at least temporarily during the calibration process. The invention further relates to a composite component ().

Method for producing a composite component, and composite component

Certain preferred embodiments of the present invention relate to compositions for the production of sintered molded parts, components/parts produced therefrom, and methods for preparing such compositions. In accordance with certain embodiments, compositions for production of sintered molded parts comprise a metal-based, a ceramic-based, and/or a polymer-based powder, and a compaction aid, having 25 to 60 weight percent of a polyglycol, based on the total weight of the compaction aid, and 40 to 75 weight percent of a montan wax, based on the total weight of the compaction aid. The compaction aid may be present in an amount from about 0.1 to 5 weight percent, preferably 0.5 to 1.5 weight percent, based on the total weight of the composition. The composition may also include a lubricant such as, for example, MoS, WS, BN, MnS, and/or carbon.
