Alliage dur fritté.
La présente invention est relative . des perfec- tionnemments apportés aux outils et autres instruments de travail constitués en alliage dur qui comporte du carbure de zirconium et un métal additionnel dont le point de fusion est beaucoup plus bas que celui du carbure dezirconium.
La Société demanderesse a constaté que de tels alliages offrent une dureté excellente, une grande résistance 1 l'usure et une très bonne solidité aussi bien 1 la température ordinaire qu'à des températures élevées. Cet alliage est particulièrement approprié pour la fabrication d'outils de coupe (pour le perçage,
<Desc/Clms Page number 2>
le tournage, le fraisage, etc...) et aussi pour d'autres outils comme, par exemple, les filières, les matrices de compression à chaud, etc...
Des métaux additionnels comme, par exemple, le cobalt, le nickel, le fer, le manganèse, le chrome, etc.. peuvent être ajoutés séparément ou en mélange, et leur quantité dépend de l'application envisagée de l'alliage.
Le pourcentage de ces métaux peut être assez élevé; il peut atteindre jusqu'à 30 % du total et même davantage.
Lorsqu'on augmente ce pourcentage, on rend l'alliage plus tenace, mais on réduit sa dureté.
On peut fabriquer les alliages conformes à l'invention, par exemple, de la façon suivante: le carbure de zirconium peut être obtenu par chauffage de l'oxyde de zirconium et du carbone dans un four électrique à 2300 C, rempli d'une atmosphère d'hydrogène. Apres quoi, cette substance à l'état de poudre peut être mélangée avec un métal additionnel, par exemple, 10% de cobalt. Le mélange est ensuite pressé et fritté à une température de 18500, par exemple. Le frittage peut être effectué en même temps que le pressage. Lorsqu'on effectue ces deux opérations simultanément, on obtient une dureté légèrement supérieure à celle qu'on peut obtenir par des opérations successives.
Il va de soi que les indications données cidessus ne constituent que des exemples, et qu'on peut s'en écarter tout en restant dans le domaine de la présente invention.

Hard sintered alloy.
The present invention is relative. improvements to tools and other working instruments made of a hard alloy which includes zirconium carbide and an additional metal whose melting point is much lower than that of zirconium carbide.
The Applicant Company has found that such alloys offer excellent hardness, high wear resistance and very good strength both at room temperature and at high temperatures. This alloy is particularly suitable for the manufacture of cutting tools (for drilling,
<Desc / Clms Page number 2>
turning, milling, etc ...) and also for other tools such as, for example, dies, hot compression dies, etc ...
Additional metals such as, for example, cobalt, nickel, iron, manganese, chromium, etc. can be added separately or as a mixture, and their amount depends on the intended application of the alloy.
The percentage of these metals can be quite high; it can reach up to 30% of the total and even more.
When we increase this percentage, we make the alloy more tenacious, but we reduce its hardness.
The alloys according to the invention can be made, for example, as follows: zirconium carbide can be obtained by heating zirconium oxide and carbon in an electric furnace at 2300 C, filled with an atmosphere of hydrogen. After that, this powdered substance can be mixed with an additional metal, for example 10% cobalt. The mixture is then pressed and sintered at a temperature of 18,500, for example. Sintering can be carried out at the same time as pressing. When these two operations are carried out simultaneously, a hardness slightly greater than that which can be obtained by successive operations is obtained.
It goes without saying that the indications given above constitute only examples, and that it is possible to depart from them while remaining within the scope of the present invention.
