Die auf die erforderliche Form gepresste Pulvermischung unter Berücksichtigung des Schrumpfens wird auf eine Graphitunterlage gelegt und frei ohne Druck in einem Durchlaufofen bei einer Temperatur von 10900 C gesintert. Die Sinterzeit richtet sich nach dem Gewicht des Erzeugnisses.

auf eine Graphitunterlage gelegt und frei ohne Druck in einem Durchlaufofen bei einer Temperatur von 10400 C gesintert. Die Sinterzeit richtet sich nach dem Gewicht des Erzeugnisses.
Das erfindungsgemässe Sinterhartmetall ist gegen Abschliff widerstandsfähiger als bekannte Sinterhartmetalle. Es kann somit vorteilhaft als Einbettungsmittel von Diamantspitzen in einem Kopf eines Gerätes zum Messen der Härte verschiedener Materialien, als Einbettungsmittel von Diamantkörnern bei Erzeugung von Bohrwerkzeugen. z. B. für geologische Forschungen, als Einbettungsmittel von Diamantstaub bei der Erzeugung von Abrichtschleifwerkzeugen u. ähnl. und überall, wo bisher die hohe Sintertemperatur die Anwendung von Sinterhartmetallen unmöglich machte, verwendet werden.
PATENTANSPRÜCHE :
1. Sinterhartmetall, insbesondere für die Erzeugung von Diamantwerkzeugen, das ein Carbid we- nigstens eines der schwerschmelzenden Metalle der IV-VI Gruppe des Periodensystems und wenigstens ein Metall aus der Gruppe der Eisenmetalle als Bindemittel enthält, dadurch gekennzeichnet, dass es bis zu 5 Gel.-% Phosphor enthält.

The powder mixture, pressed to the required shape, taking shrinkage into account, is placed on a graphite base and sintered freely without pressure in a continuous furnace at a temperature of 10900 C. The sintering time depends on the weight of the product.

placed on a graphite base and freely sintered without pressure in a continuous furnace at a temperature of 10400 C. The sintering time depends on the weight of the product.
The cemented carbide according to the invention is more resistant to abrasion than known cemented carbides. It can thus be used advantageously as an embedding medium for diamond tips in a head of a device for measuring the hardness of various materials, as an embedding medium for diamond grains when producing drilling tools. z. B. for geological research, as an embedding medium for diamond dust in the production of dressing tools and. similar and wherever the high sintering temperature previously made the use of cemented carbides impossible.
PATENT CLAIMS:
1. Sintered carbide, especially for the production of diamond tools, which contains a carbide at least one of the refractory metals of the IV-VI group of the periodic table and at least one metal from the group of ferrous metals as a binder, characterized in that it contains up to 5 gel .-% contains phosphorus.
