Description

Hochbleihaltige Lagermetall-Legierung. Die Erfindung betrifft Legierungen, die sich als Lagermetalle gut eignen und im wesentlichen aus etwa 8o Prozent Blei, to bis 15 Prozent Antimon und 5 bis r o Prozent Zinn bestehen, wozu noch geringe Zusätze von Kupfer kommen können.Bearing metal alloy with a high lead content. The invention relates to alloys that are well suited as bearing metals and consists essentially of about 8o percent lead, up to 1 to 5 percent of antimony and from 5 to ro consist percent tin, to which small additions may come from copper.

Solche hochbleihaltigen Lagermetall-Legierungen können durch einen Zusatz von Phosphor, der in bekannter Weise unmittelbar oder als Zwischenlegierung (wie- Phosphor-Kupfer, Phosphor - Mangan - Kupfer, Phosphor-Zink, Phosphor-Messing) eingeführt werden kann, verbessert werden., und zwar sowohl hinsichtlich der Erhöhung der Härtie der Legierungen wie auch der Betriebssicherheit der Lager.Such high-lead bearing metal alloys can by a Addition of phosphorus in a known manner directly or as an intermediate alloy (like- phosphorus-copper, phosphorus-manganese-copper, phosphorus-zinc, phosphorus-brass) can be introduced, improved., both in terms of increase the hardness of the alloys as well as the operational reliability of the bearings.

Eine weitere Verbesserung der Eigenschaften dieser Legierungen kann gemäß vorliegender Erfindung durch einen Zusatz von Eisen erzielt werden. Versuche haben ergeben, daß durch den Zusatz geringer Mengen Eisen (bis zu r Prozent) die Sprödigkeit der Legierung außerordentlich herabgesetzt und die Zähigkeit - erhöht wird. Diese Wirkung ist wohl darauf zurückzuführen, daß die ziemlich großen Kristalle der Härtekörper der Legierung durch den Zusatz von Eisen fein zerteilt werden, so daß sich ein feineres C;efüge der Legierung ergibt.A further improvement in the properties of these alloys can be can be achieved according to the present invention by adding iron. try have shown that by adding small amounts of iron (up to r percent) the The brittleness of the alloy is greatly reduced and the toughness is increased will. This effect is probably due to the fact that the rather large crystals the hardness of the alloy can be finely divided by the addition of iron, so that a finer carbon structure of the alloy results.
