Description
Gesinterte Hartmetallegierung für Arbeitsgeräte und Werkzeuge Zur Herstellung von Arbeitsgeräten und Werkzeugen werden vielfach gesinterte Hartmetallegierüngen benutzt, die aus einem Carbid schwer schmelzbarer Metalle und einem zusätzlichen Hilfsmetall von wesentlich niedrigerem Schmelzpunkt, wie Eisen, Kobalt öder Nickel, bestehen. Als höher schmelzender Anteil - der Legierung wurde bisher in Praxis vornehmlich Wolframcarbid benutzt, da die unter Benutzung von Wolframcarbid hergestellten Hartmetallegierungen die günstigsten Eigenschaften hinsichtlich Härte, Festigkeit und Zähigkeit aufweisen und den unter Benutzung - anderer Carbide schwer schmelzbarer Metalle, wie beispielsweise Molybdäncarbid, Ttancarbid und Siliciumcarbid, hergestellten Hartmetallegierungen weit überlegen :sind.Sintered hard metal alloy for implements and tools Zur Sintered hard metal alloys are often used in the manufacture of equipment and tools used, which consists of a carbide of difficult-to-melt metals and an additional Auxiliary metal with a significantly lower melting point, such as iron, cobalt or nickel, exist. As a higher-melting portion - the alloy has so far mainly been used in practice Tungsten carbide is used as the hard metal alloys made using tungsten carbide have the most favorable properties in terms of hardness, strength and toughness and those using other carbides of difficult-to-melt metals, such as Molybdenum carbide, titanium carbide and silicon carbide, produced hard metal alloys far superior: are.
Erfindungsgemäß wurde festgestellt, daß bei derartigen aus einem Carbid schwer schmelzbarer Metalle und einem leichter schmelzenden Hilfsmetalle bestehenden Hartmetallegierungen die Anforderungen an große Härte und ausreichende Festigkeit und Zähigkeit auch erfüllt werden, wenn der höher schmelzende Anteil der Legierung aus einem Gemisch von Vanadincarbid und Niob- oder Täntalcarbid besteht. Gegebenenfalls: können dem Vanadincarbid auch gleichzeitig Niobcarbd und Tantalcarbid zugemischt werden. Wie sich durch eingehende Versuche ergeben hat, wird bei einer derart zusammengesetzten Hartmetallegierung die große Härte durch das Niob- oder Tantalcarbid, die große Zähigkeit dagegen durch das Vanadincarbid hervorgerufen, wobei durch die Gegenwart des letzteren gleichzeitig die durch das Vorhandensein des Niob- oder Tantalcarbides hervorgerufene Sprödigkeit weitgehend beseitigt wird.According to the invention it was found that in such a carbide difficult-to-melt metals and a more easily-melting auxiliary metal Carbide alloys meet the requirements for great hardness and sufficient strength and toughness are also met when the higher melting portion of the alloy consists of a mixture of vanadium carbide and niobium or tantalum carbide. Possibly: niobium carbide and tantalum carbide can also be added to the vanadium carbide at the same time will. As has been shown by extensive experiments, such a composite Hard metal alloy the great hardness due to the niobium or tantalum carbide, the great Toughness against it caused by the vanadium carbide, whereby by the presence of the latter at the same time that due to the presence of niobium or tantalum carbide caused brittleness is largely eliminated.
Als besonders zweckmäßig hat sich eine bei etwa aooo° C gesinterte Legierung erwiesen, die unter Zusatz von 2,5 % bis 5 % Eisen oder Kobalt zu gleichen Teilen aus Vänadincarbid und 1?iobcarbid besteht. Je nachdem eine größere Zähigkeit oder Härte des Fertigerzeugnisses erwünscht ist, kann im Carbidgemisch entweder der Anteil des Vanad'incarbides oder der Anteil des Niobcarbides bzw. Tantalcarbides überwiegen. -Die Menge des beigegebenen leichter schmelzenden Zusatzmetalls kann bis auf 25 % - der Gesamtmenge der Legierung gesteigert werden. Das Sintern der Legierung kann anschließend an das Pressen des als Ausgangsmaterial verwendeten Pulvergemisches oder auch gleichzeitig mit dem Pressen erfolgen.One that has been sintered at about aooo ° C. has proven to be particularly useful Alloy proved to be the same with the addition of 2.5% to 5% iron or cobalt Parts consists of vanadium carbide and 1? Iobcarbide. Depending on the case, a greater toughness or hardness of the finished product is desired, in the carbide mixture either the proportion of vanadium carbide or the proportion of niobium carbide or tantalum carbide predominate. -The amount of added easier melting filler metal can can be increased up to 25% - of the total amount of the alloy. The sintering of the Alloy can then be used as a starting material after pressing Powder mixture or take place simultaneously with the pressing.
