Gleitlagerverbundwerkstoff mit einer Trägerschicht aus Stahl und einer darauf unlösbar aufgebrachten Gleitschicht aus AlZn5Pb4Sil , 5CuIMg bekannt geworden.Sliding bearing composite material with a carrier layer made of steel and a non-detachably applied sliding layer made of AlZn5Pb4Sil, 5CuIMg.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen umweltfreundlichen Gleitlagerverbundwerkstoff der eingangs genannten Art bereitzustellen, dessen Aluminiumlagerlegierung gut vergießbar und umformbar ist und die aber tribologisch hervorragende Eigenschaften aufweist .The present invention has for its object to provide an environmentally friendly sliding bearing composite material of the type mentioned, whose aluminum bearing alloy good pourable and formable and has but tribologically excellent properties.

Diese Aufgabe wird erfindungsgemäß durch einen Gleitlagerverbundwerkstoff mit den Merkmalen des beigefügten Anspruchs 1 gelöst .This object is achieved by a sliding bearing composite material having the features of the attached claim 1.

Es wurde erfindungsgemäß festgestellt , dass auf den Zusatz von Blei verzichtet werden kann, wenn Wismut im beanspruchten Bereich, also in einem gewichtsprozentualen Anteil von weniger als 2 , 5 Gew. -% zugesetzt wird und wenn ein Zinkgehalt von 4 , 4 bis 6 Gew. -% , vorzugsweise von wenigstens 5 Gew. -% vorgesehen wird. Es wird davon ausgegangen, dass das Zusammenwirken von Wismut im genannten gewichtsprozentualen Bereich mit feinen Ausscheidungen von Zink im mit Zink übersättigten Aluminium-Mischkristall , eine dem Schmierstoff Blei im wesentlichen nahezu gleichwirkende Eigenschaft als gleitreibungsvermindernder Zusatz , also als Schmiermittel entfaltet . Diese Erkenntnis war keinesfalls naheliegend, da sich - wie vorstehend erwähnt - wismuthaltigeIt has been found according to the invention that it is possible to dispense with the addition of lead if bismuth is added in the claimed range, ie in a weight percentage of less than 2.5% by weight and if a zinc content of 4.4-6% by weight is added. %, preferably of at least 5% by weight. It is believed that the interaction of bismuth in said weight percent range with fine precipitates of zinc in the zinc-supersaturated aluminum mixed crystal, a substantially equal to the lubricant lead unfolds property as sliding friction reducing additive, so as a lubricant. This finding was by no means obvious since - as mentioned above - bismuth-containing

Aluminiumlagerlegierungen bislang gerade durch den Zusatz von Blei erst ausgezeichnet haben. - Zwar wäre es an sich wünschenswert, Wismut in größeren Mengen, also von mehr als 2 , 5 Gew. -% zuzusetzen; es wurde aber erkannt , dass Wismut solchenfalls beim Stranggießen in der Schmelze im flüssigen Zustand tropfenförmig ausgeschieden wird und beim anschließenden Walzprozess an sich unerwünschte Wismut-Zeilen bildet . Dem könnte zwar durch Überhitzen der Schmelze entgegengewirkt werden, was den Gießprozess , einschließlich der Abkühlung aber wiederum aufwendiger gestaltet . Wenn Wismut im beanspruchten gewichtsprozentualen Bereich zugesetzt wird, insbesondere von 1 , 5 Gew. -% bis weniger als 2 , 5 Gew. -% , so lässt sich der Gießvorgang gut beherrschen und die beim Walzen sich ausbildenden Wismut-Zeilen sind deutlich kürzer und feiner . In dem beanspruchten Gleitlagerverbundwerkstoff erweist sich Wismut als hervorragender Festschmierstoff , der im Zusammenwirken mit Zink auch in dieser Konzentration zufriedenstellende Ergebnisse liefert .Aluminum bearing alloys have so far just been distinguished by the addition of lead. - Although it would be desirable to add bismuth in larger quantities, ie more than 2, 5 wt -%; However, it was recognized that bismuth is precipitated drop-wise in the liquid state in the liquid state during continuous casting and forms unwanted bismuth lines in the subsequent rolling process. Although this could be counteracted by overheating the melt, which in turn makes the casting process, including cooling, more complicated. If bismuth is added in the claimed weight percentage range, in particular from 1.5% by weight to less than 2.5% by weight, the casting process can be well controlled and the bismuth lines forming during rolling are markedly shorter and finer , In the claimed sliding bearing composite, bismuth proves to be excellent solid lubricant, which, in combination with zinc, gives satisfactory results even in this concentration.

Durch Lösungsglühen und unmittelbar anschließendes Abschrecken werden vorzugsweise Ausscheidungen von Zink mit einer Teilchengröße von weniger als 10 um erreicht .Solution heat treatment and subsequent quenching preferably results in precipitation of zinc having a particle size of less than 10 microns.

Eine bevorzugte Zusammensetzung einer bleifreien Aluminiumlagerlegierung ist gegeben durch AlZn5Bi2Sil , 5CuIMgI .A preferred composition of a lead-free aluminum bearing alloy is given by AlZn5Bi2Sil, 5CuIMgI.

Auch die neben Zink und Wismut weiteren Bestandteile Silizium, Kupfer und vor allem Magnesium sind für die zufriedenstellenden und vorteilhaften Eigenschaften des erfindungsgemäßen Gleitlagerverbundwerkstoffs wesentlich . So wirkt Magnesium verfestigend; es bildet mit Aluminium die intermetallische Phase Al3Mg2. Kupfer bildet in vorteilhafter Weise die intermetallische Phase Al2Cu . Hierdurch wird die Festigkeit des Aluminium-Mischkristalls erhöht , was darauf zurückgeführt wird, dass die Bestandteile den Kristall verspannen und damit stabilisieren und hart machen . Also, in addition to zinc and bismuth other ingredients silicon, copper and especially magnesium are essential for the satisfactory and advantageous properties of the sliding bearing composite material according to the invention. This is how magnesium acts as a hardening agent; it forms the intermetallic phase Al 3 Mg 2 with aluminum. Copper advantageously forms the intermetallic phase Al 2 Cu. As a result, the strength of the aluminum mixed crystal is increased, which is attributed to the fact that the components tense the crystal and thus stabilize and harden.
