Description

Künstliche Ersatzteile für das Innere des menschlichen oder tierischen Körpers, insbesondere Ersatzkauwerkzeuge, sowie Nadeln für ärztliche, insbesondere zahnärztliche Zwecke Es ist bereits mit gutem Erfolg vorgeschlagen worden, künstliche Ersatzteile für das Innere des menschlichen oder tierischen Körpers, insbesondere Ersatzkauwerkzeuge (einschließlich ihrer Befestigungsteile), sowie Nadeln (Nervnadeln, Sonden u. dgl.) für ärztliche, insbesondere zahnärztliche Zwecke aus chemisch neutralen austenitischen Chrom-Nickel-Stahl-Legierungen herzustellen, die hohe Widerstandsfähigkeit gegen Rosten und den Angriff von Säuren besitzen.Artificial replacement parts for the interior of the human or animal Body, in particular replacement chewing tools, and needles for medical, in particular Dental Purposes It has already been suggested with good success, artificial Spare parts for the interior of the human or animal body, in particular Replacement chewing tools (including their fastening parts), as well as needles (nerve needles, Probes and the like) for medical, especially dental purposes made of chemically neutral Austenitic chromium-nickel-steel alloys produce the high resistance against rusting and the attack of acids.

Es hat sich nun in überraschender Weise herausgestellt, daß sich zur Herstellung künst-Iicher Ersatzteile und Nadeln besonders Chrom-Nickel-Legierungen bzw. Chrom-Nickel-Stahl-Legierungen eignen, die höchstens ¢o % Chrom und bis zu 6 % Tantal, Niob, Zirkon, Uran, Hafnium oder seltene Erdmetalle, wie Cerium, Thorium, Lanthan, Ittrium, Neodym, Samarium usw., einzeln oder gemischt enthalten. Die hohe Eignung beruht darauf, daß durch den entsprechend bemessenen Zusatz an Tantal, Niob usw. der gesamte Kohlenstoff abgebunden wird, wodurch die Legierung auch nach einer einer Anlaßbehandlung gleichkommenden Erwärmung auf etwa 5oo bis goo° gegen den Angriff von Säuren oder Salzlösungen beständig bleibt, ohne dabei brüchig zu werden. Diese günstige Eigenschaft ist für den bezeichneten Verwendungszweck von großer Wichtigkeit, weil bei der Verarbeitung der Legierung zu den oben aufgeführten Gegenständen Hartlötungen, die eine Erwärmung des Werkstückes bis zu goo° bedingen, oft vorgenommen werden müssen. Außerdem bereitet das Hartlöten von Chrom-Nickel- bzw. Chrom-Nickel-Stahl-Legierungen, die mit Tantal, Niob usw. legiert sind, nicht die Schwierigkeit wie bei den entsprechenden Legierungen ohne diese Legierungskomponenten. -Als Beispiel seien Stahllegierungen genannt, die außer der bis zu 6 % betragenden zusätzlichen Legierungskomponente 12 bis 40 % Chrom, 7 bis z 5 % Nickel und bis zu i % Kohlenstoff enthalten.It has now been found in a surprising way that the Manufacture of artificial spare parts and needles, especially chrome-nickel alloys or chrome-nickel-steel alloys are suitable that contain a maximum of ¢ o% chrome and up to 6% tantalum, niobium, zirconium, uranium, hafnium or rare earth metals such as cerium, thorium, Contains lanthanum, ittrium, neodymium, samarium, etc., individually or mixed. The height Suitability is based on the fact that the appropriate addition of tantalum, niobium etc. all the carbon is bound, making the alloy even after a a tempering treatment equivalent to warming to about 5oo to goo ° against the It remains resistant to attack by acids or salt solutions without becoming brittle. This favorable property is of great importance for the intended use Importance because when processing the alloy into the items listed above Hard soldering, which causes the workpiece to heat up to goo °, is often carried out Need to become. In addition, the brazing of chrome-nickel or chrome-nickel-steel alloys, which are alloyed with tantalum, niobium, etc., do not have the same difficulty as the corresponding ones Alloys without these alloy components. Steel alloys are an example called, apart from the additional alloy component amounting to up to 6% Contains 12 to 40% chromium, 7 to 5% nickel and up to 1% carbon.

Als besonders geeignet für die Zwecke der Erfindung haben sich Stahllegierungen mit 12 bis 40 0f0 Chrom, 7 bis 25 0/lo Nickel, bis zu i % Kohlenstoff; bis zu 6 % Tantal und solche mit etwa 18 % Chrom, 8 % Nickel, 0,07 bis o,2 % Kohlenstoff; 0,3 bis 2,5 0,Eo Niob + Tantal sowie solche mit etwa 18 % Chrom, 8 % Nickel, 0,07 bis o,2 % Kohlenstoff und o,2 bis 2,5 % Zirkon erwiesen. Aus diesen Legierungen hergestellte Gegenstände lassen sich einwandfrei hart löten und sind trotz des Hartlötens in allen Teilen korrosionsbeständig. Außerdem sind sie sehr gut polierfähig.Steel alloys with 12 to 40% chromium, 7 to 25% nickel, up to 1% carbon have proven to be particularly suitable for the purposes of the invention; up to 6% tantalum and those with about 18% chromium, 8% nickel, 0.07 to 0.2% carbon; 0.3 to 2.5 0, Eo niobium + tantalum as well as those with about 18% chromium, 8% nickel, 0.07 to 0.2% carbon and 0.2 to 2.5% zirconium have been proven. Objects made from these alloys can be hard-soldered properly and, despite the hard-soldering, are corrosion-resistant in all parts. They are also very easy to polish.
