Description
Verwendung einer Kobalt-Titan-Chrom-Nickel-Legierung für allgemein chirurgische und dentale Prothetik Für die Herstellung von metallischen Zahnprothesen und von implantaten in der Chirurgie werden Kobalt-Chrom-Molybdän-Legierungen verwendet, da diese Legierungen bei hoher Zugfestigkeit von etwa 90 kp/mm2 noch eine ausreichende Dehnung von, etwa 8 % bei guter Verträglichkeit im menschlichen Körper besitzen. Die Zusammensetzung der Legierungen liegt überwiegende bei 27 bis 31 % Cr, 4,5 bis 6,5 % Mo. bis zu 1 % Mn und Be, bis zu 0,5 % C, W und Si, Rest Kobalt, wobei teilweise noch Nickel, Aluminium und Vanadin eingehalten von 0,5 bis 4 % vorhanden sind. Berner kommt noch eine Legierung dieses Typs zum Einsatz, die einen niedrigeren Chromgehalt von etwa 22 %hat und etwa 20 % Ni, 7 % Mo. 3 % Mn, 3,5 % Cu und 0,9 % Be enthält. Diese letzte Legierung hat einige technologisch bessere Kennwerte, ist Jedoch wegen des Berylliumgehaltes möglicherweise etwas toxisch. In der Regel wird das Erschmelzen und Vergießen der Ausgangslegierungen in Vakuum- oder Schigzgas-Schmelazggregaten und die Herstellung der Prothesen und Implantaten in Schutzgasanlagen zur Erzielung einer höheren Reinheit und Gasfreiheit durchgeführt.Use of a cobalt-titanium-chromium-nickel alloy for general Surgical and dental prosthetics For the production of metallic dentures and for implants in surgery, cobalt-chromium-molybdenum alloys are used, because these alloys with a high tensile strength of around 90 kp / mm2 still have a sufficient Elongation of about 8% with good tolerance in the human body. The composition of the alloys is predominantly 27 to 31% Cr, 4.5 to 6.5% Mo. up to 1% Mn and Be, up to 0.5% C, W and Si, the remainder cobalt, with some nickel, aluminum and vanadium are still present in a level of 0.5 to 4%. Bernese an alloy of this type is used, which has a lower chromium content of about 22% and contains about 20% Ni, 7% Mo, 3% Mn, 3.5% Cu and 0.9% Be. This last alloy has some technologically better characteristics, but is due to the beryllium content may be somewhat toxic. Usually this is melting and casting the starting alloys in vacuum or smoke gas melting units and the production of prostheses and implants in protective gas systems to achieve carried out with a higher purity and freedom from gas.
Die vorliegende Erifindung beruht auf der Verwendung einer titanhaltigen Kobaltbasislegierung zur Ersielung höherer Dehnungewerte bei gleicher oder auch besserer Zugfestigkeit.The present invention is based on the use of a titanium-containing one Cobalt-based alloy to achieve higher elongation values with the same or also better tensile strength.
En wurde nämlich überraschenderweise gefunden, daß eine Kobalt-Legierung mit 5 bis 15% Cr, 5 bis 15% Ni, Gehalten biß zu 1 % an C, Si, Mn und Pe bei Titagehlten zwischen 4 und 10 % ausgezeichnete Dehnungswerte bei guten Zugfestigkeiten erreicht.In fact, it was surprisingly found that a cobalt alloy with 5 to 15% Cr, 5 to 15% Ni, contents up to 1% of C, Si, Mn and Pe in titanium powder between 4 and 10% excellent elongation values with good tensile strengths.
So hat z. B. eine Legierung mit 8 % Ti, 6 % Cr, 10 % Ni, 0,015 y C, Rest Co folgende Eigenschaften im Gußzustand: 0,2-Dehngrenze 56,9 bis 76,6 kp/mm2 Zugfestigkeit 86,2 bis 109,0 kp/mm2 Dehnung 12,5 bis 17,6 % Brinellhärte 330 bis 380 kp/mm2 Patentanspruch;So has z. B. an alloy with 8% Ti, 6% Cr, 10% Ni, 0.015 y C, The remainder Co has the following properties in the as-cast state: 0.2 yield strength 56.9 to 76.6 kp / mm2 Tensile strength 86.2 to 109.0 kp / mm2 elongation 12.5 to 17.6% Brinell hardness 330 to 380 kp / mm2 claim;
