Description
Die Erfindung betrifft ein Bauteil einer Brennkraftmaschine nach der im Oberbegriff von Anspruch 1 näher definierten Art. Des weiteren betrifft die Erfindung ein Verfahren zur Herstellung eines Bauteils einer Brennkraftmaschine.The The invention relates to a component of an internal combustion engine according to in the preamble of claim 1 closer Furthermore, the invention relates to a method for producing a component of an internal combustion engine.
In Bauteilen von Brennkraftmaschinen, wie beispielsweise Zylinderköpfen oder Kolben, tritt bei einer zyklischen thermischen Belastung häufig das Problem auf, dass durch eine Behinderung der thermischen Ausdehnung von höher belasteten Bereichen in diesen Bereichen so hohe induzierte mechanische Spannungen auftreten, dass in diesen Bereichen aufgrund der starken Plastifizierung und der damit einhergehenden Materialermüdung eine Rissbildung auftritt. Diese Behinderung der thermischen Ausdehnung kommt dadurch zustande, dass das thermisch höher belastete Material dazu tendiert, sich stärker auszudehnen als das thermisch weniger stark belastete Material. Da sich die thermisch höher belasteten Bereiche meist in der Mitte des Bauteils befinden, ist eine solche Ausdehnung nach außen nicht möglich und es kommt zu den genannten Spannungen, insbesondere zu Druckspannungen, die sich beim Abkühlprozess in Zugspannungen umwandeln, die die Materialfestigkeit überschreiten können.In Components of internal combustion engines, such as cylinder heads or Piston, often occurs at a cyclic thermal load the problem on that by hindering the thermal expansion of charged higher Areas in these areas so high induced mechanical stresses occur in these areas due to the strong plasticization and the associated fatigue occurs cracking. This hindrance of thermal expansion comes about as a result of that the thermally higher loaded material tends to expand more than thermally less heavily loaded material. As the thermally charged higher Areas mostly located in the middle of the component is one such Extension to the outside not possible and it comes to the said voltages, in particular to compressive stresses, during the cooling process into tensile stresses that exceed the material strength can.
Bei aus dem allgemeinen Stand der Technik bekannten Lösungen wird versucht, über eine Verbesserung der Gießtechnik und eine nachfolgende Wärmebehandlung ein möglichst feines und sta biles Gefüge einzustellen. Diese Maßnahmen wirken sich jedoch jeweils auf das gesamte Bauteil aus, so dass die oben angesprochenen Probleme durch diese Maßnahmen nicht beseitigt werden können.in Become known from the general state of the art solutions tried over an improvement of the casting technique and a subsequent heat treatment one possible fine and stable structure adjust. These measures However, each affect the entire component, so that the above-mentioned problems are not eliminated by these measures can.

Es ist Aufgabe der vorliegenden Erfindung, ein verbessertes Verfahren zur Herstellung von Bauteilen mit verbessertem Versagensverhalten unter unterschiedlich hohen thermischen Belastungen über verschiedene Bereiche des Bauteils bereit zustellen.It Object of the present invention, an improved method for the production of components with improved failure behavior under different high thermal loads over different Provide areas of the component.
Erfindungsgemäß wird diese Aufgabe durch die in Anspruch 1 genannten Merkmale gelöst.According to the invention this Problem solved by the features mentioned in claim 1.
Erfindungsgemäß weist der thermisch höher belastete Bereich des Bauteils einen geringeren Wärmeausdehnungskoeffizienten als der thermisch weniger belastete Bereich auf, was dazu führt, dass sich das gesamte Bauteil bei einer Temperaturerhöhung gleichmäßig ausdehnen kann. Dadurch, dass sich sämtliche Bereiche des erfindungsgemäßen Bauteils gleichmäßig ausdehnen, kommt es zu keiner Dehnungsbehinderung und somit zu keinem Eintreten in den plastischen Verformungsbereich, sodass bei einer Erwärmung mit anschließender Abkühlung im wesentlichen keine bzw. nur sehr geringe Spannungen in dem Bauteil entstehen, wodurch letztendlich die ansonsten vorhandene Gefahr der Rissbildung aufgrund des Überschreitens der zulässigen Spannungen nicht gegeben ist.According to the invention the thermally charged higher Area of the component has a lower coefficient of thermal expansion as the thermally less loaded area, which leads to that evenly expand the entire component with a temperature increase can. In that all Areas of the component according to the invention stretch evenly, there is no stretch inhibition and thus no occurrence in the plastic deformation area, so when heated with followed by Cooling essentially no or only very low voltages in the component arise, which ultimately creates the otherwise existing danger cracking due to exceeding the permissible Tension is not given.
Durch die erfindungsgemäße Adaptierung des thermischen Ausdehnungskoeffizienten an die thermischen Gegebenheiten innerhalb des Bauteils kann somit das Eintreten einer Materialermüdung und/oder einer Rissbildung zu einem späteren Zeitpunkt bzw. zu höheren Belastungen verschoben werden, so dass das erfindungsgemäße Bauteil bei Brennkraftmaschinen mit höheren Leistungen und/oder einer verlängerten Lebensdauer eingesetzt werden kann.By adapting the coefficient of thermal expansion according to the invention to the thermal conditions within the component, it is therefore possible to shift the occurrence of material fatigue and / or cracking at a later point in time or at higher loads, so that the component according to the invention achieves higher outputs in internal combustion engines and / or a prolonged life can be used.
Ein Verfahren zur Herstellung eines erfindungsgemäßen Bauteils ergibt sich aus den Merkmalen von Anspruch 1.One Method for producing a component according to the invention results from the features of claim 1.
Dabei wird das Grundmaterial des Bauteils aufgeschmolzen und es wird ein Zusatzmaterial hinzugefügt, welches zu dem veränderten Wärmeausdehnungskoeffizienten in dem thermisch höher belasteten Bereich führt. Diese Vorgehensweise ermöglicht eine besonders genaue Kontrolle der Legierungszusammensetzung in dem thermisch höher belasteten Bereich.there the base material of the component is melted and it becomes a Additional material added, which changed to that CTE in the thermally higher burdened area leads. This procedure allows a particularly precise control of the alloy composition in the thermally higher charged area.
