Description
Nickel-Chrom-Legierung Die Erfindung betrifft eine Verbesserung der im Hauptpatent 616858 beschriebenen Metallegierung für chirurgische Instrumente, die neben hoher chemischer Widerstandsfähigkeit mit guter Warm- und Kaltverarbeitung härtbar ist und eine hohe Schneidfähigkeit besitzt.Nickel-chromium alloy The invention relates to an improvement of the metal alloy described in the main patent 616858 for surgical instruments, which, in addition to high chemical resistance, can be hardened with good hot and cold processing and has a high cutting ability.
Es wurde gefunden, daß die in dem Hauptpatent 616 858 hervorgehobenen Eigenschaften, die die dort beschriebene Metallegierung besitzt, keine Einbußen erleiden, wenn man das Chrom 'auf einen Gehalt unter io % beschränkt oder gänzlich wegläßt. Das in Wegfall kommende Chrom wird durch die entsprechende Menge Nickel und/oder zum Teil auch durch Mangan, Kupfer, Titan, Aluminium bis zu Mengen von io % ersetzt. Der Tantalgehalt bleibt in seiner vollen Höhe erhalten. Bedingung ist, daß das Tantal in Verbindung mit Kohlenstoff, wie im Hauptpatent bereits angedeutet, als Tantalkarbid vorhanden ist. Es ist zweckmäßig, das Tantal mit dem Kohlenstoff in Form von Tantalkarbid der Legierung zuzusetzen.It has been found that those highlighted in main patent 616,858 Properties that the metal alloy described there has, no loss suffer if the chromium is limited to a content below 10% or entirely omits. The chromium that is omitted is replaced by the corresponding amount of nickel and / or partly also by manganese, copper, titanium, aluminum up to amounts of io% replaced. The tantalum content is retained in full. condition is that the tantalum in connection with carbon, as already indicated in the main patent, is present as tantalum carbide. It is useful to combine the tantalum with the carbon to be added to the alloy in the form of tantalum carbide.
Es ist erfindungsgemäß erkannt, daß das Tantalkarbid der Träger der Schnei.dhärte in der chemisch widerstandsfähigen Grundmasse ist. Dadurch, daß es mit keinem der vorhandenen Metallelemente der Grundmasse chemische Umsetzungen eingeht, bleibt das Tantälkarbid in fein verteilter Form in der Metallmasse enthalten. Die Schneidwirkung ist so zu erklären, daß das sehr harte Karbid von der Schneide (einst und gleichmäßig verteilt ist und das Instrument daher sägend arbeitet.It is recognized according to the invention that the tantalum carbide is the carrier of Snow hardness is in the chemically resistant base material. By doing it does not undergo chemical reactions with any of the existing metal elements of the matrix, the tantalum carbide remains in finely divided form in the metal mass. the The cutting effect can be explained by the fact that the very hard carbide of the cutting edge (once and is evenly distributed and the instrument therefore works like a saw.
Durch die genannten Zusätze an Chrom bis höchstens io °/o oder bei gänzlichem Wegfall von Chrom, auch an Mangan und Kupfer, Aluminium und Titan bis io °1o wird die Festigkeit der Grundmasse erhöht. Das Mangan wirkt noch nebenbei günstig für die Kaltverformung. Kupfer erhöht auch noch die chemische Widerstandsfähigkeit und insbesondere die Widerstandsfähigkeit gegen organische Säuren. Titan erhöht ebenfalls die Härte der Grundmasse, übt aber weiter noch einen sehr günstigen Einfluß auf die chemische Widerstandsfähigkeit aus. Mit der steigenden Menge des Tantals ist auch zwecks Erhöhung der Schneidhärte eine Erhöhung des Kohlenstoffgehaltes bis maximal q. % sehr vorteilhaft.With the above-mentioned additions of chromium up to a maximum of 10% or at Complete elimination of chromium, including manganese and copper, aluminum and titanium up to io ° 1o the strength of the base mass is increased. The manganese also works on the side favorable for cold forming. Copper also increases chemical resistance and especially the resistance to organic acids. Titan increased also the hardness of the base mass, but still has a very beneficial influence on chemical resistance. With the increasing amount of tantalum is also an increase in the carbon content for the purpose of increasing the cutting hardness up to a maximum of q. % very advantageous.
Verwendung findet die Legierung für Gegenstände, die chemisch und mechanisch widerstandsfähig sein sollen, im besonderen für alle stechenden und, schneidenden medizinischen Instrumente, einschließlich Injektionskanülen, Nervnadeln, Sonden und Skalpelle, die neben einer hohen Festigkeit noch eine hohe -Elastizität und Kerbzähigkeit besitzen müssen. Auch für Körperersatzteile und Ersatzkauwerkzeuge findet die Legierung sinngemäß Anwendung. .The alloy is used for objects that are chemically and should be mechanically resistant, especially for all piercing and, cutting medical instruments, including hypodermic needles, nerve needles, Probes and scalpels, in addition to high strength one must have high elasticity and notch toughness. Also for body spare parts and replacement chewing tools, the alloy is used accordingly. .
