Abstract
Description
Die Erfindung betrifft eine Gußeisenlegierung für die Herstellung von Kolbenringen für Verbrennungskraftmaschinen mit hoher Temperaturbelastung.The invention relates to a cast iron alloy for the production of piston rings for Internal combustion engines with high temperature loads.
Kolbenringe für Verbrennungskraftmaschinen bestehen überwiegend aus grauen Gußeisenlegierungen mit Anteilen an kugelförmigen bis lamellaren Graphitausscheidungen. Insbesondere die in der obersten, dem Verbrennungsraum benachbarten Kolbennut angeordneten Kolbenringe sind hohen Temperaturen ausgesetzt, so daß von ihnen mechanische Festigkeitswerte mit hoher Temperaturbeständigkeit verlangt werden. Nach beispielsweise der DE-OS 36 28 157 verwendet man eine kugelgraphitische Gußeisenlegierung mit martensitischem Grundgefüge für auf hohe Temperaturen belastete Kolbenringe, welche 1 bis 15 Gewichtsprozent im Grundgefüge in Kugel- bis Tröpfchenform ausgeschiedenes Kupfer enthält, das auf Grund seiner hohen Wärmeleitfähigkeit für eine schnelle Wärmeableitung und damit für eine verminderte Temperaturbelastung des Kolbenringwerkstoffes sorgt.Piston rings for internal combustion engines mainly consist of gray ones Cast iron alloys with proportions of spherical to lamellar Graphite precipitates. Especially the one in the top, the combustion chamber adjacent piston grooves are exposed to high temperatures, so that mechanical strength values of them with high temperature resistance be requested. According to DE-OS 36 28 157 one is used spheroidal graphite cast iron alloy with martensitic basic structure for high Piston rings exposed to temperatures, which have 1 to 15 percent by weight in the basic structure Contains copper excreted in spherical to droplet form high thermal conductivity for quick heat dissipation and thus for a reduced temperature load on the piston ring material.
Nach der DE-OS 39 29 804 sind Gußeisenlegierungen mit ferritischem bis perlitischem Grundgefüge und kugelgraphitischen Ausscheidungen aus 3,0-3,6 Gewichtsprozent Kohlenstoff, 1,5-3,0 Gewichtsprozent Silizium, 0,6-1,3 Gewichtsprozent Mangan, 0,6 -1,0 Gewichtsprozent Kupfer, 0,4-0,8 Gewichtsprozent Chrom, 0,1-0,3 Gewichtsprozent Aluminium, 0,03-0,1 Gewichtsprozent Mangan und Eisen als Rest bekannt, die für verschleißbeanspruchte Maschinenteile wie offenen Verzahnungen in Mahlanlagen oder spanenden Werkzeugen eingesetzt werden. Diese Gußeisenlegierungen sind jedoch nicht für Verschleißteile in thermisch hochbelasteten Verbrennungskraftmaschinen vorgesehen. Insbesondere in modernen Verbrennungskraftmaschinen werden zur Verbesserung des Fahr-, Lauf- und Geräuschkomforts bei gleichzeitig deutlicher Leistungssteigerung Kurz-huber mit Leichtbau-Kastenkolben eingesetzt, bei denen zur Erzielung eines vibrationsarmen Laufs die Kolbenringbestückungen extrem nach oben verlegt sind. Insbesondere der oberste Kolbenring und zum Teil auch der zweite sogenannte Abstreifring werden dadurch höheren Temperaturen ausgesetzt, so daß von ihrem Werkstoff mechanische Festigkeitswerte mit verbesserter Temperaturbeständigkeit verlangt werden. Die Warmfestigkeit der aus der DE-OS 36 28 157 bekannten martensitischen Gußeisenlegierungen reicht für derartig hohe Beanspruchungen nicht aus.According to DE-OS 39 29 804 are cast iron alloys with ferritic to pearlitic Basic structure and spheroidal graphite deposits from 3.0-3.6 percent by weight Carbon, 1.5-3.0 weight percent silicon, 0.6-1.3 weight percent manganese, 0.6 -1.0 weight percent copper, 0.4-0.8 weight percent chromium, 0.1-0.3 Weight percent aluminum, 0.03-0.1 weight percent manganese and iron as the balance known for machine parts subject to wear and tear such as open gears in Grinding plants or cutting tools are used. This Cast iron alloys, however, are not for wear parts in high thermal loads Internal combustion engines provided. Especially in modern ones Internal combustion engines are used to improve driving, running and Noise comfort with a significant increase in performance Lightweight box pistons used to achieve a low-vibration run the piston ring assemblies are placed extremely upwards. Especially the top one Piston ring and partly also the second so-called scraper ring are thereby exposed to higher temperatures, so that their material is mechanical Strength values with improved temperature resistance are required. The Heat resistance of the martensitic known from DE-OS 36 28 157 Cast iron alloys are not sufficient for such high demands.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Gußeisenlegierung für hohen Temperaturen ausgesetzten Kolbenringe von Verbrennungskraftmaschinen mit bei hohen Temperaturen beständigen Festigkeitswerten zu finden.The present invention is therefore based on the object of a cast iron alloy for internal combustion engine piston rings exposed to high temperatures to find stable strength values at high temperatures.

und deren aus der Legierung gegossene Werkstücke ganzflächig oder an den Laufflächen
und/oder den Flankenflächen nach einem der üblichen Verfahren einer Nitrierbehandlung
unterzogen sind. Mit den erfindungsgemäßen Gußeisenlegierungen werden probeweise
an den Laufflächen nitrierte Kolbenringe hergestellt, die zur Ermittlung über
Warmfestigkeit Temperaturen zwischen 500-700°C durch Glühbehandlungen während
30 Minuten ausgesetzt wurden. Es wurde ein normaler Abfall der Härtewerte festgestellt,
ohne daß die perlitische Grundstruktur der Gußeisenlegierung wesentlich verändert
wurde. Die Festigkeitswerte wurden durch diese Temperaturbelastung nicht wesentlich
verändert, so daß der Werkstoff die geforderte hohe Warmfestigkeit besitzt.According to the invention, this object is achieved by a cast iron alloy with a pearlitic basic structure and spherical or vermicular graphite precipitates, which consists of

With the cast iron alloys according to the invention, nitrided piston rings are produced on a trial basis, which were exposed to temperatures between 500-700 ° C. by annealing treatments for 30 minutes to determine their heat resistance. A normal decrease in hardness values was found without the basic pearlitic structure of the cast iron alloy being changed significantly. The strength values were not significantly changed by this temperature load, so that the material has the required high heat resistance.

Bearbeitbarkeit kann die Gußeisenlegierung einer Glühbehandlung bei bis zu 750°C
unterzogen werden. Die Kolbenringe können zur Verbesserung ihrer Verschleißfestigkeit
ganzflächig oder an den Laufflächen und/oder den Flankenflächen nach einem der
üblichen Verfahren wie Badnitrieren, Gasnitrieren, Plasmanitrieren oder
Pulsplasmanitrieren einer Nitrierbehandlung unterzogen werden. Dabei werden
bevorzugt die erfindungsgemäßen Gußeisenlegierungen mit an der oberen Gehaltsgrenze
