Description

Metallformlinge Es ist bekannt, Metallpulver mit Harr. oder Kunstharz zu verpress:en und durch Wärmeeinwirkung das Harr. auszuhärten, so daß ein Formling entsteht, dessen Festigkeit ungefähr jener des Harzes entspricht, die für die häufigsten Verwendungsgebiete, wie Massekerne, Preßmagnete u. d-1., genügt.Metal moldings It is known to use metal powder with Harr. or synthetic resin to be pressed: and by the action of heat the Harr. to harden, so that a molding arises, the strength of which corresponds approximately to that of the resin used for the most common Areas of application, such as mass cores, press magnets and d-1., Are sufficient.

Es ist auch schon bekannt, gesinterte Metallteile mit öl, Paraffin u. dgl. zu tränken, um ein geeignetes Material für selbstschmierende Lager herzustellen.It is also already known to sintered metal parts with oil, paraffin and the like to make a suitable material for self-lubricating bearings.

Es wurde nun gefunden, daß man Metallformlinge mit hoher mechanischer Festigkeit und günstigem Korrosionsverhalten sowie auch günstigen Gleitegenschaften erhalten kann, wenn man .den gesinterten Metallformling mit flüssigen Harzen oder Harzbestandteilen tränkt und diese z. B. durch Erw.-irmeii aushärtet. Die so erhaltenen Metallfurmlinge verbinden eine Festigkeit, die etwa 4o bis 75°1'o des vollen Metalls beträgt, mit einer sehr hohen Korrosionsfestigkeit. Ferner sind sie in den meisten Fällen für massive Lager besonders geeignet, da der gesinterte metallische Grundkörper durch seine Festigkeit das Traggerüst bildet, zwischen welchem die weiche, lauffähige Harzmasse liegt.It has now been found that metal moldings with high mechanical Strength and favorable corrosion behavior as well as favorable sliding properties can be obtained if one .the sintered metal molding with liquid resins or Soaks resin components and these z. B. hardened by adult irmeii. The so obtained Metal fragments combine a strength that is about 4o to 75 ° 1'o that of full metal with a very high corrosion resistance. They are also in most of them Cases particularly suitable for massive bearings, as the sintered metallic base body its strength forms the supporting structure, between which the soft, runnable Resin mass lies.

Für die Herstellung von Schliffen von porösen Massen, insbesondere von keramischen Massen, ist zur mikroskopischen Untersuchung bereits vorgeschlagen worden, diese Massen in Kunstharz einzubetten, zu härten und .anschließend zu schleifen. Auf diese Art werden Faber keine Formlinge im Sinne der Erfindung, bei denen es .auf hohe mechanische Festigkeit und hohen Korrosionswiderstand ankommt, erhalten.For the production of sections of porous masses, in particular of ceramic masses has already been proposed for microscopic examination been to embed these masses in synthetic resin, to harden and then to grind. In this way, Faber will not produce any briquettes within the meaning of the invention in which there is .High mechanical strength and high corrosion resistance are important.
