Description

Verwendung von Palladium-Legierungen für elektrische Unterbrecherkontakte Zusatz zum Patent 961762 Die Erfindung bezieht sich auf eine weitere Ausgestaltung der im Patent 961762 beschriebenen Verwendung einer Legierung aus 0,1 bis 25% Blei und, oder 0.1 bis 28% Zinn, Rest Palladium, wobei dic Summe dieser beiden Zusätze vorzugsweise zwischen 5 und 15% liegt, als Werkstoff für elektrische Unterbrecherkontakte.Use of palladium alloys for electrical breaker contacts Addition to patent 961762 The invention relates to a further embodiment of the use described in patent 961762 of an alloy of 0.1 to 25% lead and, or 0.1 to 28% tin, the remainder palladium, where dic The sum of these two additives is preferably between 5 and 15% as a material for electrical breaker contacts.

In weiterer Entwicklung des Hauptpatentes haben sich wertvolle und bis jetzt unbekannte Variationsmöglichkeiten zur weiteren Verbesserung der im Hauptpatent unter Schutz. gestellte Verwendung dieser Legierung ergeben.In further development of the main patent, valuable and Up to now unknown variation possibilities for further improvement of the main patent under protection. Asked use of this alloy result.

Es hat sich nämlich herausgestellt, (laß außer deii im Hauptpatent zur Verwendung bei elektrischen Kontakten beschriebenen Palladium-Blei- und Palladium-Zinn-Legierungen auch Legierungen zwischen Palladium und dem der Gruppe IV des Periodischen Systems angehörenden Metalls Germanium sowie zwischen Palladium und den schweren Metallen der III. Gruppe des Periodischen System, nämlich Indium, Gallium, Thallium, für die Verwendung bei elektrischen Kontakten besonders geeignet sind. An Stelle oder neben Blei und Zinn können also auch eines oder mehrere der eben genannten 1-letalle aus der III. und/oder der I#.". Gruppe des Periodischen Svstems treten.It turned out that (except for deii in the main patent Palladium-lead and palladium-tin alloys described for use in electrical contacts also alloys between palladium and that of group IV of the periodic table belonging metal germanium as well as between palladium and the heavy metals the III. Group of the Periodic Table, namely Indium, Gallium, Thallium, for are particularly suitable for use with electrical contacts. Instead of or In addition to lead and tin, one or more of the 1-lethal substances just mentioned can also be used from the III. and / or the I #. ". group of the Periodic System.

yAls besonders geeignet für diese Verwendung haben sich Palladium-Kontaktwerkstoffe mit Zusätzen von Indium erwiesen. Auch hier besteht auf der Palladium-Seite des Zustandschaubildes ein _Mischkristallgebiet, das sich bis rund 20% Indium erstreckt. Kontakte aus Legierungen dieses Gebietes zeigen bei ihrer Verwendung in Kontakten eine außergewöhnlich geringe Materialwanderung und einen .ehr niedrigen Übergangswiderstand, der zudem über längere Zeitr iiume völlig konstant bleibt.yPalladium contact materials have proven to be particularly suitable for this use with the addition of indium. Again, there is on the palladium side of the State diagram of a solid solution area that extends to around 20% indium. Alloy contacts of this area show when used in contacts an exceptionally low material migration and a very low contact resistance, which also remains completely constant over a longer period of time.

Der Indiumgehalt kann sich in den Grenzen von 0.1 bis 20 Gewichtsprozent bewegen und wird zweckmäßig von 5 bis 15 Gewichtsprozent Inditiin gewählt.The indium content can range from 0.1 to 20 percent by weight move and is expediently chosen from 5 to 15 percent by weight inditiin.

Ähnliche Eigenschaften wie Indiuni haben die chemisch verwandten Elemente Gallium und Tlialliuni. Das Iridium kann also ganz oder teilweise (lunch Gallium, Thallium oder Germanium ersetzt sein, und außerdem können alle diese genannten Elemente Beineinsam mit den im I-Tatiptpatent beanspruchten Eleinenten Blei und Zinn zusammen mit Palladium legiert sein. Ausführungsbeispiele l . Palladium ......... 90 Gewichtsprozent Iridium ............ 10 Gewichtsprozent 2. Palladium ......... 85 Gewichtsprozent Inditim ............ 12 Gewichtsprozent Thallitim .......... 3 Ge-,vichtsprozent 3. Palladium ......... 92 Gewichtsprozent Indium ............ d Gewichtsprozent Blei ............... -1 Gewichtsprozent . Palladium ......... 87 Gewichtsprozent Germanium ........ 2 Gewichtsprozent Indium ............ 5 Gewichtsprozent Silber ............. 6 Gewichtsprozent Auch bei diesen 1_egierungen können ebenso wie bei den Legierungen des Hauptpatentes teilweise all Stelle des Palladiums ein oder mehrere der Metalle Kupfer, Silber, :Nickel und Kobalt treten, sofern durch diesen Zusatz nicht ein anderer Legierungsbestandteil, wie z. B. (las Iridium, zur Ausscheidung aus dem --Mischkristall gebracht wird, und zwar beträgt dabei (leg (Gehalt an Kupfer oder Silber 1 bis 250/n. der an Nickel und/oder Kobalt bis zu 10%.The chemically related elements gallium and tlialliuni have similar properties to indiuni. The iridium can thus be completely or partially replaced (lunch gallium, thallium or germanium, and in addition all these elements mentioned can be alloyed together with the elements lead and tin claimed in the I-Tatipt patent together with palladium. Embodiments l. Palladium ......... 90 percent by weight Iridium ............ 10 percent by weight 2. Palladium ......... 85 percent by weight Inditim ............ 12 percent by weight Thallitim .......... 3 weight percent 3. Palladium ......... 92 percent by weight Indium ............ d percent by weight Lead ............... -1 weight percent . Palladium ......... 87 percent by weight Germanium ........ 2 percent by weight Indium ............ 5 percent by weight Silver ............. 6 percent by weight With these 1_alloys, as with the alloys of the main patent, one or more of the metals copper, silver, nickel and cobalt can sometimes occur in all places of the palladium, provided that this addition does not result in another alloy component, such as e.g. B. (las iridium is made to precipitate out of the solid solution, namely (leg (content of copper or silver 1 to 250 / n. That of nickel and / or cobalt up to 10%.
