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 konstanten 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 gezwungen, auf andere Legierungspartner auszuweichen. Es 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 To be able to meet resistances. Unfortunately, such alloys are very heavy; you are therefore forced to switch to other alloy partners. It is already known to alloy palladium with tungsten or molybdenum. Such alloys are however, it is only readily deformable with a relatively low tungsten or molybdenum content, while To achieve high resistance values, higher alloy contents are also necessary.
Ferner sind Legierungen aus je 0,5 bis 15% Ruthenium und Kupfer, Rest Palladium, Legierungen aus 10 bis 6011/o Platin, 12 bis 899/o Palladium, 1 bis 15% Ruthenium und/oder Rhodium, Legierungen aus 10 bis 80% Platin, 12 bis 90'0!o Palladium, 1 bis 150/0 Ruthenium, Legierungen aus 80 bis 90% Palladium, 5 bis 10% Rhodium, 5 bis 109/o Iridium, Legierungen aus 60 bis 95% Palladium, 0,5 bis 2011/a Ruthenium, 2,5 bis 39,5 9/o Iridium bekannt.There are also alloys of 0.5 to 15% ruthenium and copper, the rest Palladium, alloys of 10 to 6011 / o platinum, 12 to 899 / o palladium, 1 to 15% Ruthenium and / or rhodium, alloys from 10 to 80% platinum, 12 to 90'0! O palladium, 1 to 150/0 ruthenium, alloys of 80 to 90% palladium, 5 to 10% rhodium, 5 to 109 / o iridium, alloys from 60 to 95% palladium, 0.5 to 2011 / a ruthenium, 2.5 to 39.5 9 / o iridium is known.
Es wurde nun gefunden, daß Legierungen des Palladiums mit Titan, Zirkonium, Hafnium, Thorium, Vanadin, Niob oder Tantal, einzeln oder zu mehreren, vorzügliche elektrische, mechanische und chemische Eigenschaften besitzen, die sie insbesondere für Potentiometerwiderstände hoher Güte ausgezeichnet geeignet machen. Nach der Erfindung wird als Werkstoff für elektrische Widerstände, insbesondere für Potentiometer, eine Legierung aus 1 bis 50, vorzugsweise 3 bis 4011/o der genannten Elemente, Rest Palladium, benutzt. Als besonders interessant haben sich Legierungen des Vanadins mit Palladium, gegebenenfalls mit Gehalten von Gold oder Silber, erwiesen, die sich relativ leicht bearbeiten lassen.It has now been found that alloys of palladium with titanium, zirconium, Hafnium, thorium, vanadium, niobium or tantalum, individually or in groups, excellent have electrical, mechanical and chemical properties that make them in particular make them ideally suited for high-quality potentiometer resistors. After Invention is used as a material for electrical resistors, especially for potentiometers, an alloy of 1 to 50, preferably 3 to 4011 / o of the elements mentioned, remainder Palladium, used. Vanadium alloys have proven to be of particular interest with palladium, possibly with contents of gold or silver, proved that can be processed relatively easily.
In manchen Fällen ist es auch erwünscht, bis zu 3011/o, vorzugsweise bis zu 1511/o, der in der Legierung vorhandenen Palladiummenge durch Silber und/oder Gold zu ersetzen.In some cases it is also desirable, up to 3011 / o, preferably up to 1511 / o, the amount of palladium present in the alloy by silver and / or To replace gold.
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.
