  Verfahren zur Herstellung von Legierungen mit grosser Härte, hohem Verschleisswiderstand und guter Schneidkraft. 



   Durch eingehende Versuche wurde nachgewiesen, dass   Kobalt-Molybdän-Legierungen   durch eine besondere thermische Behandlung gehärtet werden können. Erhitzt man Kobaltlegierungen mit 10-35% Molybdän im gegossenen oder gewalzten Zustand auf eine oberhalb etwa 1000  C gelegene Temperatur, kühlt sie darauf an der Luft oder durch Eintauchen in Wasser oder Öl hinreichend schnell ab und erhitzt sie schliesslich bei Temperaturen zwischen   500-900  C,. so   steigert man die Festigkeitseigenschaften 
 EMI1.1 
 Zustand auf 215 Brinelleinheiten. Gegebenenfalls kann man diesen vergütbaren Legierungen auch Zusätze von einem oder mehreren andern Elementen, wie Kupfer, Aluminium, Nickel, Chrom, Mangan, bis zu   40%   hinzufügen.

   Auch bei derartigen Legierungen kann man durch eine geeignete thermische Behandlung, wie sie oben angegeben wurde, die Festigkeitseigenschaften erheblich steigern. 



   PATENT-ANSPRÜCHE :
1. Verfahren zur Herstellung von Legierungen mit grosser Härte, hohem Versehleisswiderstand und guter Schneidkraft, die auch bei höheren Temperaturen erhalten bleiben, aus Kobalt-MolybdänLegierungen mit   10-35% Molybdän, dadurch gekennzeichnet,   dass die Legierungen von einer oberhalb etwa 1000  C gelegenen Temperatur rasch abgekühlt und anschliessend bei Temperaturen zwischen   500-900  C   angelassen werden.

  Process for the production of alloys with great hardness, high wear resistance and good cutting force.



   Extensive tests have shown that cobalt-molybdenum alloys can be hardened through a special thermal treatment. If cobalt alloys with 10-35% molybdenum are heated in the cast or rolled state to a temperature above about 1000 C, they are then cooled sufficiently quickly in the air or by immersion in water or oil and finally heated at temperatures between 500-900 C. ,. this increases the strength properties
 EMI1.1
 Condition on 215 Brinelle units. If necessary, additions of one or more other elements, such as copper, aluminum, nickel, chromium, manganese, up to 40% can also be added to these heat treatable alloys.

   With such alloys, too, the strength properties can be increased considerably by a suitable thermal treatment, as indicated above.



   PATENT CLAIMS:
1. Process for the production of alloys with great hardness, high wear resistance and good cutting force, which are retained even at higher temperatures, from cobalt-molybdenum alloys with 10-35% molybdenum, characterized in that the alloys are from a temperature above about 1000 C. cooled quickly and then tempered at temperatures between 500-900 C.
