Description

material für Reibungsbeanspruchung unterworfene, vorzugsweise elektrischen Strom führende Teile von technischen Anordnungen Es ist bereits vorgeschlagen worden, als Material für Reibungsbeanspruchung unterworfene, vorzugsweise- elektrischen Strom führende Teile von technischen Anordnungen, wie z. B. Lager, Kollektoren, Schleifkontakte von Maschinen oder Apparaten, eine Kupfer-Beryllium-Legierung zu verwenden, die mehr Kupfer als Beryllium und außerdem gegebenenfalls noch Zusätze anderer Elemente enthält.material for frictional stress, preferably electrical Current-carrying parts of technical arrangements It has already been proposed as a material subject to frictional stress, preferably electrical Live parts of technical arrangements, such as B. Storage, collectors, Sliding contacts of machines or devices, a copper-beryllium alloy too use more copper than beryllium and possibly additives contains other elements.

Die Erfindung betrifft die Anwendung von Legierungen mit überwiegendem Nickel-, Kobalt- oder Eisengehalt und Beryllium für den gleichen Zweck. Von diesen Berylliumlegierungen war zwar schon früher erkannt, daß sie eine verhältnismäßig hohe Härte und Festigkeit durch eine besondere thermische Behandlung erhalten können. Diese physikalischen Eigenschaften ermöglichten durchaus nicht ohne weiteres einen sicheren Rückschluß auf das Verhalten derartiger Legierungen als Material für Reibungsbeanspruchung unterworfene Teile von- technischen Anordnungen. Erst durch Versuche ließ sich eindeutig diese Frage klären.The invention relates to the use of alloys with predominantly Nickel, cobalt or iron content and beryllium for the same purpose. Of these Beryllium alloys were recognized earlier to be a proportionate high hardness and strength can be obtained through a special thermal treatment. These physical properties did not make one possible at all reliable conclusion on the behavior of such alloys as a material for frictional stress Subject to parts of technical arrangements. It was only through experiments that it became clear clarify this question.

Will man eine Nickel-Beryllium-Legierung für den angegebenen Zweck verwenden, so kann man durch thermische Behandlung dieser eine Härte von etwa 55o Brinell erteilen bei hoher Korrosionsbeständigkeit. Durch thermische Behandlung einer Eisen-Beryllium-Legierung kann man die Härte bis zu etwa 6oo Brinell steigern, während bei einer Kobalt-Beryllium-Legierung Härten bis zu etwa 65o Brinell erreichbar sind.One wants a nickel-beryllium alloy for the stated purpose use, you can get a hardness of about 55o by thermal treatment Brinell grant high corrosion resistance. Through thermal treatment an iron-beryllium alloy, the hardness can be increased up to about 6oo Brinell, while hardnesses of up to about 65o Brinell can be achieved with a cobalt-beryllium alloy are.

Die thermische Behandlung kann in allen Fällen in einer Erhitzung der Legierung in bestem Zustand auf mehrere hundert Grad und in einer nochmaligen Erhitzung auf niedrigere, z. B. etwa halb so hoch wie zuvor liegende Temperaturen, bestehen. Nach der ersten Erhitzung wird zweckmäßig eine schnelle Abkühlung vorgenommen werden. Gegebenenfalls können in den Legierungen außer den angegebenen Elementen auch noch Zusätze anderer Elemente, wie Zinn, Zink, Aluminium usw., vorhanden sein, ohne daß dadurch ihre Verwendbarkeit beeinträchtigt wird.The thermal treatment can in all cases consist of heating of the alloy in the best condition to several hundred degrees and in one more Heating to lower, e.g. B. about half as high as the previous temperatures, exist. After the first heating, rapid cooling is expediently carried out will. If necessary, the alloys can contain the specified elements there are also additions of other elements, such as tin, zinc, aluminum, etc., without affecting their usability.

Wie aus den angegebenen Beispielen ersichtlich ist, eignet sich das neue Material gut für die Herstellung von Reibungsbeanspruchung unterworfene Teile von Maschinen oder Apparaten aller Art, da es zufolge seiner hohen Härte, Festigkeit und Korrosionsbeständigkeit den für diese Zwecke sonst üblichen Materialien "-mindestens gleichwertig ist. Bei Verwendung als zugleich elektrischen Strom führende Teile-kommt der günstigste Umstand hinzu, daß durch die thermische Behandlung die elektrische Leitfähigkeit gesteigert wird.As can be seen from the examples given, this is suitable new material good for the manufacture of frictional parts of machines or apparatus of all kinds, as it is according to his high Hardness, strength and resistance to corrosion are those otherwise usual for these purposes Materials "- is at least equivalent. When used as at the same time electrical Live parts - the most favorable fact is that by the thermal Treatment increases the electrical conductivity.
