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 load.
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 consist predominantly of gray Cast iron alloys with proportions of spherical to lamellar Graphite separations. Especially in the top, the combustion chamber adjacent piston groove arranged piston rings are exposed to high temperatures, so that they have mechanical strength values with high temperature resistance be requested. For example, DE-OS 36 28 157 uses a spherical graphitic cast iron alloy with martensitic basic structure for on high Temperatures loaded piston rings, which 1 to 15 weight percent in the basic structure contained in spherical to droplet form copper due to its high thermal conductivity for rapid heat dissipation and thus for a Reduced temperature load of the piston ring material ensures.
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.In particular, in modern internal combustion engines are used to improve the Driving, running and noise comfort at the same time clearly increased performance short huber used with lightweight box pistons in which to achieve a low-vibration run the piston ring assemblies are laid extremely upwards. In particular, the uppermost piston ring and partly also the second so-called Wiper rings are thus exposed to higher temperatures, so that of their Material mechanical strength values with improved temperature resistance be requested. The heat resistance known from DE-OS 36 28 157 Martensitic cast iron alloys are not sufficient for such high stresses out.
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, a cast iron alloy For high temperature exposed piston rings of internal combustion engines with to find stable strength values at high temperatures.
Erfindungsgemäß wird diese Aufgabe durch eine Gußeisenlegierung mit perlitischer Grundstruktur und kugelförmigen oder vermikularförmigen Graphitausscheidungen gelöst, welche ausAccording to the invention this object is achieved by a cast iron alloy with pearlitic Basic structure and spherical or vermicular graphite precipitates solved, which out

Mit den erfindungsgemäßen Gußeisenlegierungen werden probeweise Kolbenringe gegossen, 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. With the cast iron alloys according to the invention are trial piston rings cast to determine the heat resistance temperatures between 500-700 ° C were exposed by annealing treatments for 30 minutes. It became one normal drop of the hardness values determined, without the pearlitic basic structure of the Cast iron alloy was significantly changed. The strength values were through this Temperature load is not changed significantly, so that the material required has high heat resistance.
