Abstract

The invention discloses a jacketed wire having a platinum jacket which encases a core composed of an alloy of 1 to 5% by weight of tungsten, the remainder being palladium. The jacket volume per length unit is 10 to 50% of the total volume of the jacketed wire. These jacketed wires are produced by drawing a rod-tube arrangement. The jacketed wires are preferably used as supply-lead wires for resistance thermometers having a platinum measurement resistor.

Description

Die Erfindung bezieht sich auf einen Manteldraht mit einem Mantel aus Platin, der einen Kern aus einem edelmetallhaltigen Werkstoff umhüllt, auf ein Verfahren zur Herstellung solcher Manteldrähte sowie auf deren Verwendung.The invention relates to a sheathed wire with a sheath made of platinum, which encases a core made of a precious metal-containing material Process for the production of such sheathed wires and their use.

Es sind seit vielen Jahren Widerstandsthermometer im Handel erhältlich, bei denen mit dem im wesentlichen aus Platin bestehenden Meßwiderstand ein Manteldraht als Zuleitungsdraht für die Stromzuleitung unverrückbar verbunden, insbesondere verschweißt, ist. Der Zuleitungsdraht besteht aus einem Mantel aus Platin, der einen Kern aus einer Gold-Legierung, die 5 Gewichts-% Platin enthält, umhüllt. Diese bekannten Manteldrähte weisen gute mechanische Eigenschaften, wie Zugfestigkeit, Bruchdehnung und Streckfähigkeit auf. Allerdings ist ihr Preis sehr erheblich, insbesondere weil das Volumen des aus Platin bestehenden Mantels pro Längeneinheit etwa 64% des Gesamtvolumens des Manteldrahts beträgt. Man hat daher schon versucht, den Volumen-Anteil des Mantels am Gesamtvolumen des Manteldrahts zu vermindern, um dadurch den Preis des Manteldrahts zu reduzieren. Derartige Versuche schlugen jedoch fehl, weil mit der Verminderung des Mantelvolumens Verschlechterungen der mechanischen Eigenschaften des Manteldrahts einhergingen.Resistance thermometers have been commercially available for many years, at those with the measuring resistor consisting essentially of platinum Sheathed wire firmly connected as a lead wire for the power lead, especially welded. The lead wire consists of a sheath Made of platinum, which has a core made of a gold alloy, which is 5% platinum by weight contains, envelops. These known sheathed wires have good mechanical Properties such as tensile strength, elongation at break and stretchability. However, their price is very substantial, especially because of the volume of the Platinum existing jacket per unit length about 64% of the total volume of the Sheathed wire is. One has therefore already tried to determine the volume proportion of the To reduce the sheath to the total volume of the sheathed wire, thereby reducing the price to reduce the sheathed wire. However, such attempts failed because with the reduction of the jacket volume deterioration of the mechanical Properties of the sheathed wire went hand in hand.

Aus der EP-PS 00 29 888 ist die Herstellung eines Manteldrahtes bekannt, der einen Kern aus einer Zirkon-Kupferlegierung und einen Mantel aus Gold besitzt. Er wird in der Weise hergestellt, daß ein Vorratsdraht aus der Zirkon-Kupfer­ legierung gereckt, dann Gold plattiert und nach der Goldplattierung der Draht in zwei Stufen auf Enddurchmesser gereckt wird. Hierbei handelt es sich offen­ sichtlich um ein galvanisches Plattierverfahren.From EP-PS 00 29 888 the manufacture of a sheathed wire is known has a core made of a zircon-copper alloy and a jacket made of gold. It is made in such a way that a supply wire made of zircon copper alloy stretched, then gold plated and after gold plating the wire is stretched to final diameter in two stages. This is open obviously a galvanic plating process.

Der Erfindung liegt daher die Aufgabe zugrunde, einen preiswerteren Manteldraht mit Platin-Mantel zu schaffen, der zumindest gleich gute mechanische Eigenschaften wie die bekannten Manteldrähte mit Platin-Mantel und einem Kern aus einer 95 Gewichts-% Gold und 5 Gewichts-% Platin bestehenden Legierung aufweist.The invention is therefore based on the object, a cheaper To create sheathed wire with a platinum sheath that is at least equally good mechanical properties like the well-known sheathed wires with platinum sheath and a core consisting of a 95% by weight gold and 5% by weight platinum Alloy.

Gelöst wird diese Aufgabe für einen Manteldraht mit einem Mantel aus Platin, der einen Kern aus einem edelmetallhaltigen Werkstoff umhüllt, erfindungsgemäß dadurch, daß der Kern aus einer Palladium-Legierung besteht, die 1 bis 5 Gewichts-% Wolfram, Rest Palladium enthält, und daß das Mantelvolumen pro Längeneinheit 10 bis 50% des Gesamtvolumens des Manteldrahts beträgt.This task is solved for a sheathed wire with a sheath made of platinum, which encases a core made of a noble metal-containing material, according to the invention in that the core consists of a palladium alloy, the 1 to 5 % By weight tungsten, the rest contains palladium, and that the jacket volume per Unit of length is 10 to 50% of the total volume of the sheathed wire.

Bewährt hat sich besonders ein Manteldraht, der sich dadurch auszeichnet, daß der Kern aus einer Legierung aus 3 Gewichts-% Wolfram und 97 Gewichts-% Palladium besteht und daß das Mantelvolumen 30% des Gesamtvolumens des Manteldrahtes beträgt.A sheathed wire, which is characterized in that the core of an alloy of 3% by weight tungsten and 97% by weight Palladium exists and that the jacket volume 30% of the total volume of the Sheathed wire is.

Überraschenderweise haben Vergleichsuntersuchungen ergeben, daß für einen Manteldraht gemäß Anspruch 2 Zugfestigkeitswerte von 322 N/mm2, eine Streckgrenze von 125 N/mm2 und eine Bruchdehnung von 24% erreicht werden, während unter gleichen Bedingungen für einen Manteldraht mit Platin-Mantel und einem Kern aus einer Legierung, die aus 95 Gewichts-% Gold und 5 Gewichts-% Platin besteht, und dessen Mantelvolumen pro Längeneinheit 64%, bezogen auf das Gesamtvolumen des Manteldrahts, beträgt, Zugfestigkeitswerte von 229 N/mm2, eine Streckgrenze von 144 N/mm2 und eine Bruchdehnung von 17% gemessen wurden. Die Zugversuche zur Ermittlung der Zugfestigkeit-, Streckgrenzen- und Bruchdehnungswerte wurden gemäß DIN 51210 durchgeführt. Die Kosteneinsparungen für erfindungsgemäße Manteldrähte betragen etwa 1/3 der Kosten für die zu den Vergleichsversuchen herangezogenen Manteldrähte des Standes der Technik.Surprisingly, comparative tests have shown that tensile strength values of 322 N / mm 2 , a yield strength of 125 N / mm 2 and an elongation at break of 24% are achieved for a sheathed wire according to claim 2, while under the same conditions for a sheathed wire with a platinum sheath and a Core made of an alloy consisting of 95% by weight gold and 5% by weight platinum, and whose sheath volume per unit length is 64%, based on the total volume of the sheathed wire, tensile strength values of 229 N / mm 2 , a yield strength of 144 N / mm 2 and an elongation at break of 17% were measured. The tensile tests to determine the tensile strength, yield strength and elongation at break values were carried out in accordance with DIN 51210. The cost savings for inventive sheath wires are about 1/3 of the cost of the zoom drawn to the comparative experiments sheath wires of the prior art.

Außer der Kosteneinsparung hat sich überraschenderweise ergeben, daß die mechanischen Eigenschaften erfindungsgemäßer Manteldrähte gegenüber den bekannten und bewährten Vergleichs-Manteldrähten sogar verbessert sind; bei etwa gleichen Werten für die Streckgrenze liegen die Werte für die Zugfestigkeit und die Bruchdehnung um etwa 40% höher.In addition to the cost savings, it has surprisingly been found that the mechanical properties of sheathed wires according to the invention compared to  known and proven comparison sheathed wires are even improved; at The values for the are about the same values for the yield strength Tensile strength and elongation at break about 40% higher.

Die Herstellung des erfindungsgemäßen Manteldrahts mit Mantel aus Platin und einem Kern aus einer Palladium-Wolfram-Legierung erfolgt vorteilhafterweise so, daß ein stabförmiger Kern-Werkstoff aus einer Palladium-Legierung, die aus 1 bis 5 Gewichts-% Wolfram, Rest Palladium besteht, in ein Rohr aus Platin eingebracht und diese Stab-Rohr-Anordnung auf Enddraht-Durchmesser gezogen wird.The production of the sheathed wire according to the invention with a sheath made of platinum and a core made of a palladium-tungsten alloy is advantageously made so that a rod-shaped core material made of a palladium alloy 1 to 5% by weight of tungsten, rest of palladium, in a tube made of platinum introduced and drawn this rod-tube arrangement to end wire diameter becomes.

Vorteilhafterweise erfolgt der Ziehvorgang in mehreren Stufen mit jeweils einer Zwischenglühung.The drawing process advantageously takes place in several stages, each with an intermediate annealing.

Erfindungsgemäße Manteldrähte werden vorzugsweise als Zuleitungsdraht für Widerstandsthermometer mit einem aus im wesentlichen aus Platin bestehenden Meßwiderstand verwendet.Sheathed wires according to the invention are preferably used as lead wires for Resistance thermometer with one consisting essentially of platinum Measuring resistor used.
