Description
Künstliche Ersatzteile für das Innere des menschlichen oder tierischen Körpers, insbesondere Ersatzkauwerkzeuge (einschließlich ihrer Befestigungsteile) aus einer Chrom-Kobalt-Legierung Die Erfindung betrifft künstliche Ersatzteile für das Innere des menschlichen oder tierischen Körpers, insbesondere Ersatzkauwerkzeuge (einschließlich ihrer Befestigungsteile) aus einer Chrom-Kobalt-Legierung und besteht darin, daß die Legierung 6 bis 40°,o Chrom, über 6 und bis zu 30010 Wolfram oder Molybdän, o bis 20 0/0 Nickel, 0,OI bis 2%, vorzugsweise unter 0,6% Kohlenstoff und als Rest 40 bis 9° Wo Kobalt enthält.Artificial replacement parts for the interior of the human or animal Body, especially replacement chewing tools (including their fasteners) from a chromium-cobalt alloy The invention relates to artificial replacement parts for the inside of the human or animal body, especially replacement chewing tools (including their fastening parts) made of a chrome-cobalt alloy and consists in that the alloy 6 to 40 °, o chromium, over 6 and up to 30010 tungsten or Molybdenum, 0 to 20% nickel, 0, OI to 2%, preferably less than 0.6% carbon and the remainder 40 to 9 ° Wo contains cobalt.
Die beiden Metalle Wolfram und Molybdän können auch gleichzeitig vorhanden sein, mit der Maßgable, daß ihre Gesamtmenge mehr als 10%, jedoch nicht über 30% 0/0 beträgt.The two metals tungsten and molybdenum can also be present at the same time be, with the measurable that their total amount is more than 10%, but not more than 30% Is 0/0.
Es hat sich gezeigt, daß aus diesen Legierungen gefertigte Gegenstände gegen oxydierende Einflüsse, gegen den Angriff von Körpersäften (z.B. Mundsäften) und Arzneien, wie überhaupt gegen chemische Agentien (Milchsäure, Essigsäure, Fettsäure, Salzsäure, Schwefelwasserstoff usw.) sehr beständig sind und keine Wirkung auf die Geschmacksnerven ausüben. Sie sind in dieser Beziehung Teilen aus den bekannten austenitischen Chrom-Nickel Eisen-Legierungen zumindest gleichwertig, zeichnen sich aber diesen gegenüber dadurch aus, daß sie eine höhere Elastizität aufweisen und sich damit besonders in solchen Fällen eignen, in denen eine Klemmkraft ausgeübt werden soll, und daß, wenn es sich um Formgußstücke handelt, die erfindungsgemäß zu verwendenden Legierungen die Form auch bei geringen Wandstärken aufs beste ausfüllen und so die kleinsten und verwickeltsten Stücke ohne Schwierigkeit scharf abgegossen werden können. Auch lassen sich die Legierungen mit den vorzugsweise zu verwendenden niedrigen Kohlenstoffgehalten schmier den und zu Drähten verarbeiten. Ferner sind sie gut lötbar, polierbar und infolge ihrer Härte gegen Zerkratzen sehr widerstands fähig. Durch Wärmebehandlung können die Eigenschaften der Legierungen, z. B. ihre Härte, beeinflußt werden. It has been shown that articles made from these alloys against oxidizing influences, against attack by body fluids (e.g. oral juices) and medicines, as well as against chemical agents (lactic acid, acetic acid, fatty acid, Hydrochloric acid, hydrogen sulfide, etc.) are very stable and have no effect on the Exercise taste buds. In this respect they are parts of the known Austenitic chromium-nickel iron alloys, at least equivalent, stand out but this is characterized by the fact that they have a higher elasticity and are therefore particularly suitable in those cases in which a clamping force is exerted is to be, and that, if it is castings according to the invention The alloys to be used fill the shape as well as possible, even with small wall thicknesses and so the smallest and most intricate pieces are sharply cast without difficulty can be. The alloys can also be used with the low carbon contents lubricate and process into wires. Furthermore are they are easy to solder, polish and, due to their hardness, are very resistant to scratching able to. The properties of the alloys, e.g. B. theirs Hardness, to be affected.
Für die nach der Erfindung zu verwendenden Legierungen seilen folgende Beispiele genannt: I. 35 % Chrom, 7,5 % Molybdän, 0,5 Wo Kohlenstoff, Rest Kobalt. The following ropes for the alloys to be used according to the invention Examples mentioned: I. 35% chromium, 7.5% molybdenum, 0.5% carbon, the remainder cobalt.
11. 30% Chrom, 7% Wolfram, 7% Molybdän, 1 °/0 Nickel, 0,1 0/0 Kohlenstoff, Rest Kobalt. 11. 30% chromium, 7% tungsten, 7% molybdenum, 1 ° / 0 nickel, 0.1 0/0 carbon, Remainder cobalt.
