Description
Verwendung einer Edelmetallegierung als Werkstoff für Widerstände, insbesondere für Potentiometerdrähte In neuerer Zeit ist man bestrebt, hochohmige Widerstände für Potentiometer und ähnliche elektrische Geräte in ihrer Größe und ihrem Gewicht zu reduzieren. Diese Bestrebungen wurden insbesondere durch die im Flugzeugbau gestellten Forderungen eingeleitet, da hier eine Gewichtsersparnis bei der Vielzahl der verwendeten elektrischen Instrumente von großer Bedeutung sein kann. An die Werkstoffe zur Herstellung solcher Widerstände, insbesondere von Potentiometern, werden damit die verschiedensten, nur schwer zu vereinbarenden Forderungen gestellt. Sie sollen einerseits einen hohen elektrischen Widerstand, andererseits einen sehr geringen Temperaturkoeffizienten besitzen. Sie sollen abriebfest sein, aber sich gut verformen lassen. Sie müssen auch noch nach langer Betriebsdauer konstante Widerstände besitzen, wobei gleichzeitig an die Korrosionsfestigkeit außerordentlich hohe Ansprüche gestellt werden. Zu allen diesen Eigenschaften kommt noch die Forderung nach einem konstant niedrigen Übergangswiderstand.Use of a precious metal alloy as a material for resistors, especially for potentiometer wires. In recent times, efforts have been made to use high-resistance Resistors for potentiometers and similar electrical devices in their size and to reduce their weight. These efforts were particularly supported by the im Aircraft construction initiated demands, as here a weight saving the multitude of electrical instruments used can. The materials used to manufacture such resistors, especially potentiometers, This means that the most varied of demands that are difficult to reconcile are made. On the one hand they should have a high electrical resistance, on the other hand a very high one have low temperature coefficients. They are supposed to be abrasion resistant, but they are let it deform well. They still need constant resistances even after a long period of operation have, at the same time extremely high demands on the corrosion resistance be asked. In addition to all of these properties, there is also the requirement for one constant low contact resistance.
Alle diese Forderungen glaubte man bisher, zumindest zum Teil, vor allem durch die Verwendung von Platin- und Goldlegierungen als Werkstoff (für elektrische Widerstände) erfüllen zu können. Leider haben solche Legierungen ein hohes Gewicht, man ist also in gewissen Fällen gezwungen, auf andere Legierungspartner mit einem kleineren spezifischen Gewicht auszuweichen. Hierzu ist bereits bekannt, Palladium mit Wolfram oder Molybdän zu legieren. Solche Legierungen sind jedoch nur bei relativ geringen Wolfram- oder Molybdängehalten gut verformbar, während zum Erreichen hoher Widerstandswerte auch höhere Legierungsgehalte notwendig sind.All of these demands were previously believed, at least in part mainly through the use of platinum and gold alloys as material (for electrical Resistances) to be able to meet. Unfortunately, such alloys are very heavy, So in certain cases you are forced to switch to other alloy partners with a to avoid smaller specific gravity. Palladium is already known for this purpose alloy with tungsten or molybdenum. However, such alloys are only relative low tungsten or molybdenum contents easily deformable, while to achieve higher Resistance values also higher alloy contents are necessary.
Ferner sind Legierungen aus je 0,5 bis 15% Ruthenium und Kupfer, Rest Palladium, Legierungen aus 10 bis 60°/o Platin, 12 bis 89% Palladium, 1 bis 15 % Ruthenium und/oder Rhodium, Legierungen aus 10 bis 801)/o Platin, 12 bis 90% Palladium 1 bis 151)/o Ruthenium, Legierungen aus 80 bis 90% Palladium, 5 bis 101)/o Rhodium, 5 bis 10% Iridium, Legierungen aus 60 bis 95% Palladium, 0,5 bis 20% Ruthenium, 2,5 bis 39,5% Iridium bekannt.There are also alloys of 0.5 to 15% ruthenium and copper, the rest Palladium, alloys of 10 to 60% platinum, 12 to 89% palladium, 1 to 15% Ruthenium and / or rhodium, alloys of 10 to 80% platinum, 12 to 90% palladium 1 to 151) / o ruthenium, alloys of 80 to 90% palladium, 5 to 101) / o rhodium, 5 to 10% iridium, alloys of 60 to 95% palladium, 0.5 to 20% ruthenium, 2.5 to 39.5% iridium is known.
Es wurde nun gefunden, daß sich die eingangs gestellten Forderungen verhältnismäßig weitgehend erfüllen lassen, wenn man Palladium mit Uran, Rhenium oder Chrom, allein oder zu mehreren, in Mengen von 1 bis 50, vorzugsweise 3 bis 40% legiert. Dabei haben Legierungen mit einem Gehalt von weniger als 10/0 oder auch schon weniger als 3 % der erwähnten Legierungsmetalle einen unzureichenden Widerstand. Besonders günstige Erfolge werden mit der Legierungskomponente Rhenium in Mengen von 3 bis 30% erzielt, wobei sich die Verformbarkeit einer Palladium-Rhenium-Legierung bei teilweisem Ersatz des Rheniums durch Vanadium weiter verbessern läßt.It has now been found that the requirements made at the outset Can be relatively largely fulfilled if you combine palladium with uranium, rhenium or chromium, alone or in groups, in amounts of 1 to 50, preferably 3 to 40% alloyed. Alloys with a content of less than 10/0 or even less than 3% of the alloy metals mentioned are inadequate Resistance. The alloy component rhenium is particularly successful Achieved in amounts of 3 to 30%, with the deformability of a palladium-rhenium alloy with partial replacement of the rhenium by vanadium can be further improved.
In manchen Fällen ist es auch erwünscht, bis zu 30°/o, vorzugsweise bis zu 15%, der in der Legierung vorhandenen Palladiummenge durch Gold und/oder Silber zu ersetzen.In some cases it is also desirable, up to 30%, preferably up to 15% of the amount of palladium present in the alloy through gold and / or To replace silver.
Gegenüber den bekannten Legierungen zeichnen sich Legierungen gemäß der Erfindung durch ein niedrigeres spezifisches Gewicht, durch eine kleine Thermospannung gegenüber Kupfer, durch einen kleinen Temperaturkoeffizienten, durch hohe Zerreißfestigkeit und durch einen hohen spezifischen Widerstand aus, der in der Regel über 1,0 Ohm mm2/m liegt.Compared to the known alloys, alloys are distinguished according to of the invention by a lower specific weight, by a small thermal voltage compared to copper, due to a small temperature coefficient, due to its high tensile strength and characterized by a high specific resistance, which is usually above 1.0 ohm mm2 / m.
