Abstract

Abstract Translated from German Die Erfindung betrifft die Verwendung einer an sich bekannten Kobalt-Chrom-Legierung, die aus 10 bis 35% Chrom, 1 bis 10% Titan, 2 bis 15% Molybdän, Rest Kobalt einschließlich herstellungsbedingter Verunreinigungen besteht. Werkstoffe dieser Zusammensetzung werden für Prothesengerüste vorgeschlagen, die mit einer dentalen Keramik beschichtet werden. The invention relates to the use of a cobalt-chromium alloy known per se, which consists of 10 to 35% chromium, 1 to 10% titanium, 2 to 15% molybdenum, the rest cobalt including production-related impurities. Materials of this composition are proposed for denture frameworks that are coated with a dental ceramic. Vorzugsweise wählt man eine Legierung aus 2 bis 5% Titan, 3 bis 6% Molybdän, 15 bis 25% Chrom sowie ggf. 0,1 bis 3% Mangan, 0,1 bis 2% Eisen, 0,1 bis 2% Aluminium und/oder 0,1 bis 1% Silicium, Rest Kobalt, die unter Vakuum vergossen worden ist. An alloy of 2 to 5% titanium, 3 to 6% molybdenum, 15 to 25% chromium and optionally 0.1 to 3% manganese, 0.1 to 2% iron, 0.1 to 2% aluminum and / or 0.1 to 1% silicon, balance cobalt, which has been cast under vacuum.
