Use of a cast iron alloy according to one of claims 1 to 6 as a material for production Machine parts subject to high friction such as piston rings of internal combustion engines, in particular fire rings and sealing strips of rotary piston engines.

Die Erfindung betrifft eine hochverschleißfeste, Gußeisenlegierung mit lamellarer bis knötchenförmiger Graphitausscheidung.The invention relates to a highly wear-resistant cast iron alloy with lamellar to nodular graphite precipitation.

Reibend beanspruchte Maschinenelemente werden sowohl verschleißmiißig als auch thermisch stark belastet, so daß iin ihre Werkstoffe besonders hohe Anforderungen gestellt werden müssen. Bestimmte Maschinenelemente, wie beispielsweise Kolbenringe von Verbrennungskraftmaschinen, und zwar insbesondere Feuerringe, aber auch Dichtleistcn von Rotationskolbenmaschinen, stehen darüber hinaus unter besonders starker Belastung. Die Erfahrung hat gezeigt, daß diesen hohen Beanspruchungen nur sehr teure und kompliziert hergestellte Werkstoffe gewachsen sind. Dabei handelt es sich üblicherweise um Sinterhartmetalle, denen ganz definierte Legierungselemente zugegeben worden sind.Machine elements that are subjected to frictional loads are subject to high wear and tear as well as high thermal loads, so that their materials have to meet particularly high requirements must be asked. Certain machine elements, such as piston rings in internal combustion engines, in particular fire rings, but also sealing strips of rotary piston machines, are also under particularly heavy loads. Experience has shown that this high Only very expensive and complexly manufactured materials can cope with stresses. It is about usually sintered carbides to which very defined alloying elements have been added.

Die bisher erprobten Gußeisensorten sind aber für diese hochbeanspruchten Maschinenteile nicht einscizbar. Es ist bekannt, die Verschleißfestigkeit von GuBcisensorten durch Zugabe von Legicrungselcmcntcn zu steigern. Diese Elemente jedoch bilden beim Erstarren des Gußeisens relativ grobkörnige und sehr harte Karbide, die dann auf den Gegenlaufflächen unter Riefenbildung Zerstörungen hervorrufen. Gleichzeitig wird durch die Karbidbildung der größte Teil des Kohlenstoffes verbraucht, so daß diesen Legierungen der für den Notlauf dieser Maschinenelemente notwendige Graphit im Gefüge fehlt Weiterhin sind diese Werkstoffe so spröde, daß sie auch mechanischen Beanspruchungen nicht gewachsen sind und brechen.The cast iron grades that have been tried out so far cannot, however, be scaled for these highly stressed machine parts. The wear resistance of GuBcisensorten is known to be increased by the addition of legalization elements. However, these elements form upon solidification relatively coarse-grained and very hard carbides of cast iron, which then cause destruction by scoring on the mating surfaces. At the same time will most of the carbon is consumed by the carbide formation, so that these alloys are the most suitable for The graphite required for the emergency running of these machine elements is missing in the structure. These materials are also used so brittle that they can withstand mechanical stress have not grown and break.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine Gußeisenlegierung zu Finden, die verschleißfest genug gegen erhöhte Reibungsbeanspruchung ist und dabei mit dem Gegenwerkstoff eine ausreichende Verträglichkeit besitzt, die Graphitausscheidungen aufweist und die bei mechanischer Beanspruchung nicht spröde ist uud nicht brichtIt is therefore the object of the present invention To find a cast iron alloy that is wear-resistant enough against increased frictional stress and at the same time has sufficient compatibility with the mating material that exhibits graphite precipitates and which is not brittle under mechanical stress and does not break

Diese Aufgabe wird durch eine verschleißfeste Gußeisenlegierung gelöst, deren ungebundener Kohlenstoff in lamellarer bis vorwiegend knötchenförmiger Ausscheidungvorliegt und die eine große Anzahl von Karbiden beziehungsweise auch Nitriden und/oder Boridcn in fein kristalliner Ausscheidungsform besitzt.This problem is solved by a wear-resistant cast iron alloy whose unbound carbon present in lamellar to predominantly nodular excretion and a large number of carbides or nitrides and / or borides possesses in finely crystalline precipitate form.
