Description

Verwendung von Palladiumlegierungen für Dentalzwecke Die üblichen niedrig schmelzenden Legierungen, wie sie z. B. zum Löten von Zahnprothesen Verwendung finden, bestehen zum größten Teil aus Edelmetallen, die gegebenenfalls noch verhältnismäßig geringe Zusätze an geeigneten Unedelmetallen lenthalten. Die meist gebräuchlichen Dentallote sind z. B. Gold-Silber-Kupfer- und Palladium-Silber-Legierungen mit Zusätzen von Metallen, wie Zink und Cadmium.Use of palladium alloys for dental purposes The usual low-melting alloys, such as those used, for. B. use for soldering dentures find, consist for the most part of precious metals, which may still be proportionate contain small amounts of suitable base metals. The most common Dental solders are z. B. gold-silver-copper and palladium-silver alloys with additives of metals such as zinc and cadmium.

Die Erfinderin hat sich die Aufgabe gestellt, Legierungen mit verhältnismäßig geringen Edelmetallgehalten, die sich vor allem für Gußzwecke und zum Löten z.B. von Zahnersatzteilen eignen, aufzufinden. The inventor has set herself the task of making alloys with relatively low precious metal contents, which are particularly suitable for casting purposes and for soldering e.g. of dental prostheses are suitable to find.

Es wurde gefunden, daß solche Legierungen diese Zwecke in ausgezeichneter Weise erfüllen, welche 20 bis 60, vorzugsweise 30 bis 45% Palladium, Rest Eisen, Nickel, Kobalt, einzeln oder zu mehreren, enthalten. It has been found that such alloys are excellent for these purposes Way, which 20 to 60, preferably 30 to 45% palladium, remainder iron, Contains nickel, cobalt, individually or in groups.

Hierbei kann das Palladium ganz oder teilweise durch Gold und/oder Platin ersetzt sein, und zwar zweckmäßig je ein Gewichtsteil Palladium durch etwa I,3 Gewichtsteile Gold und/oder Platin.The palladium can be completely or partially replaced by gold and / or Platinum should be replaced, expediently one part by weight of palladium by about 1.3 parts by weight of gold and / or platinum.

Derartige Legierungen haben sich als sehr anlaufbeständig und widerstandsfähig gegenüber dem Angriff aggresiver Stoffe, wie sie im Mund vorkommen, erwiesen; sie zeichnen sich ferner durch eine sehr gute Gießbarkeit aus; sie sind gut bearbeitbar und eignen sich vorzüglich zum Löten von höher schmelzenden Metallteilen, z. 13. solchen aus nichtrostendem Stahl, wie V2A-Stahl oder Kobalt-Chrom-Wolfram-Legierunglen, wie sie für Zahnprothesen verwendet werden. Such alloys have proven to be very tarnish-resistant and tough against the attack of aggressive substances, as they occur in the mouth, proven; she are also characterized by very good castability; they are easy to work with and are ideal for soldering higher-melting metal parts, e.g. 13th those made of stainless steel, such as V2A steel or cobalt-chromium-tungsten alloys, how they are used for dentures.

Die Legierungen könnten die für die Gußlegierungen und Lote üblichen Zusätze, wie Kupfer, Silber, Zink, Cadmium, Mangan, Chrom, Zinn, einzeln oder zu mehreren in untergeordneten Mengen z. B. bis zu etwa 10% oder bis zu etwa 15% enthalten. The alloys could be those customary for the cast alloys and solders Additives such as copper, silver, zinc, cadmium, manganese, chromium, tin, individually or too several in subordinate quantities z. B. contain up to about 10% or up to about 15%.

Nachstehend seien einige Beispiele von Zusammensetzungen von Legierungen gemäß Erfindung angegeben: 1. 40,0% Pd 2. 25,0% Pd 54,0% Fe 25,0% Au 3,9% Cu 47,0% Fe 0,9% Mn 1,9% Cu 1,2% Zu 1,1% Zn 3. 36,0% Pd 4. 25,5% Au 58,0% Ni 49,3% fe 4,0% Cu 10,8% Noi 0,5% Mn 11,0% Cr 1,5% Zn 1,0% Cu 0,7% Mn 1,7% Zn 5. 24,0% Pd 18,0% Pt 50,5% Co 6,0% Cu 1,5% Zn Some examples of compositions of alloys are given below specified according to the invention: 1. 40.0% Pd 2. 25.0% Pd 54.0% Fe 25.0% Au 3.9% Cu 47.0% Fe 0.9% Mn 1.9% Cu 1.2% To 1.1% Zn 3. 36.0% Pd 4. 25.5% Au 58.0% Ni 49.3% Fe 4.0% Cu 10.8% Noi 0.5% Mn 11.0% Cr 1.5% Zn 1.0% Cu 0.7% Mn 1.7% Zn 5. 24.0% Pd 18.0% Pt 50.5% Co 6.0% Cu 1.5% Zn
