Metallformlinge und Verfahren zu ihrer Herstellung
Es ist bereits bekannt, Metallpulver gemischt mit Harz oder Kunstharz als Bindemittel zu verpressen und durch Wärmeeinwirkung das Harz auszuhärten, so dass ein Formling entsteht, dessen Festigkeit ungefähr jener des Harzes entspricht, die für die häufigsten Verwendungsgebiete, wie Massekerne, Pressmagnete usw., genügt.
Es ist auch schon bekannt, gesinterte Metallteile, beispielsweise aus Eisen oder Bronze, mit Öl, Paraffin u. dgl. zu tränken, um ein geeignetes Material für selbstschmierende Lager herzustellen.
Es wurde nun gefunden, dass man Metallformlinge, vorzugsweise solche aus Sintereisen, mit hoher mechanischer Festigkeit und günstigem Korrosionsverhalten, sowie auch günstigen Gleiteigenschaften erhalten kann, wenn man den gesinterten Metallformling mit flüssigen Harzen oder Harzbestandteilen tränkt und diese durch Erwärmen aushärtet. Z. B. wird ein Sintereisenkörper mit dem Raumgewicht 6-0 mit den flüssigen Bestandteilen des Kunstharzes, z. B. Resinit, getränkt und ausgehärtet. Die Tränkung geschieht bei Raumtemperatur, die Härtung erfolgt durch langsames Erhitzen auf etwa 80-100 C. Die Härtung ist frühestens

Metal moldings and processes for their manufacture
It is already known to press metal powder mixed with resin or synthetic resin as a binder and to cure the resin through the action of heat, so that a molding is created whose strength corresponds approximately to that of the resin, which is sufficient for the most common areas of use, such as mass cores, press magnets, etc. .
It is also already known to use sintered metal parts, for example made of iron or bronze, with oil, paraffin and the like. Like. To soak in order to produce a suitable material for self-lubricating bearings.
It has now been found that metal moldings, preferably those made of sintered iron, with high mechanical strength and favorable corrosion behavior, as well as favorable sliding properties, can be obtained if the sintered metal molding is impregnated with liquid resins or resin constituents and these are cured by heating. For example, a sintered iron body with a density of 6-0 is mixed with the liquid components of the synthetic resin, e.g. B. Resinite, soaked and cured. The impregnation takes place at room temperature, the hardening takes place by slow heating to about 80-100 C. The hardening is at the earliest
