Description
Gesinterte Hartmetallegierungen Zusatz zum Patent 622 347 Das Hauptpatent 622 347 befaßt sich mit einem Verfahren zur Herstellung von, für Arbeitsgeräte und Werkzeuge bestimmten Hartmetallegierungen, bei dem fein gepulvertes Wolframcarbid mit etwa 3 bis 7% Kohlenstoff mit ebenfalls fein gepulvertem Hilfsmetall (Eisen, Nickel, Kobalt) bis 25% und ebensolchem Titancarbid bis 4o% gemischt, zu Formen gepreßt und gesintert oder gleichzeitig mit dem Pressen gesintert wird. Der Zusatz von Titancarbid macht die Legierungen besonders geeignet für die Bearbeitung von Stahl und ähnlichen zähen Werkstoffen.Sintered hard metal alloys Addition to patent 622 347 The main patent 622 347 deals with a method for the production of, for tools and Tools specific hard metal alloys, in which finely powdered tungsten carbide with about 3 to 7% carbon with also finely powdered auxiliary metal (iron, Nickel, cobalt) up to 25% and the same titanium carbide up to 40% mixed to form pressed and sintered or sintered simultaneously with the pressing. The addition of titanium carbide makes the alloys particularly suitable for machining Steel and similar tough materials.
Erfindungsgemäß wurde festgestellt, daß Legierungen von gleich guter Beschaffenheit erhalten werden können, wenn an Stelle des eine sehr harte Verbindung darstellenden Titancarbids Titannitrid, Titanborid oder Titansilicid, d. h. andere harte Titanverbindungen verwendet, also der aus Wolframcarbid und niedriger schmelzendem Hilfsmetall bestehenden Legierung zusätzlich beigegeben werden. Weiter hat sich gezeigt, daß man durch zusätzliche Verwendung von Gemischen harter Titanverbindungen, beispielsweise eines Gemisches aus Titancarbid und Titannitrid, sogar noch bessere Schneidleistungen an zähen Werkstoffen erzielen kann. Die Legierungen nach vorliegender Erfindung sind also durch nachstehende Zusammensetzung gekennzeichnet: 0,2 bis 40% Titannitrid, Titanborid, Titansilicid, einzeln oder in Mischung, 0,2 bis 25%6 Eisen, Nickel oder Kobalt, Rest Wolframcarbid mit etwa 3 bis 7% Kohlenstoff, wobei ein Teil des Titannitrids, Titanborids und/oder Titansilicids durch Titan.carbid ersetzt sein kann.According to the invention it was found that alloys of equally good Texture can be obtained if in place of a very hard bond titanium carbide, titanium nitride, titanium boride or titanium silicide, d. H. other hard titanium compounds are used, i.e. those made from tungsten carbide and lower melting points Auxiliary metal can also be added to the existing alloy. Next has shown that by using mixtures of hard titanium compounds, for example a mixture of titanium carbide and titanium nitride, even better Can achieve cutting performance on tough materials. The alloys according to the present Invention are therefore characterized by the following composition: 0.2 to 40% Titanium nitride, titanium boride, titanium silicide, individually or in a mixture, 0.2 to 25% 6 iron, Nickel or cobalt, the remainder being tungsten carbide with about 3 to 7% carbon, with a Part of the titanium nitride, titanium boride and / or titanium silicide replaced by titanium carbide can be.
Eine besonders zweckmäßige Zusammensetzung der neuen Legierungen ist die folgende: 850/0 Wolframcarbid, 5% Kobalt, 7% Titancarbid, 3% Titannitrid.A particularly useful composition of the new alloys is the following: 850/0 tungsten carbide, 5% cobalt, 7% titanium carbide, 3% titanium nitride.
