Abstract
Description
Die Erfindung betrifft ein Radialverdichterlaufrad aus einem aus eine zumindest Al und Cu enthaltenden wärmeaushärtbaren Legierung bestehenden Grundwerkstoff und ein Verfahren zu seiner Herstellung.The The invention relates to a radial compressor impeller of one of a at least Al and Cu containing thermosetting alloy existing Base material and a method for its production.
Ein bekanntes Radialverdichterlaufrad für Abgasturbolader ist aus einer Al-Cu-Mg-Legierung gefertigt. Diese Legierung wird zur Wärmeaushärtung einer T6-Wärmebehandlung unterzogen. Diese Behandlung sieht vor, die Legierung zunächst für etwa drei Stunden auf eine Temperatur von etwa 500 °C zu erwärmen und dann schnell auf Raumtemperatur abzuschrecken. Anschließend wird der Werkstoff für acht Stunden auf eine Wärmeauslagerungstemperatur von etwa 180 bis 200 °C gebracht. Danach lässt man ihn auf Raumtemperatur abkühlen.One Known radial compressor impeller for exhaust gas turbocharger is made of a Made of Al-Cu-Mg alloy. This alloy is used for heat curing T6 heat treatment subjected. This treatment initially provides the alloy for about three Hours to a temperature of about 500 ° C and then quickly to room temperature deter. Subsequently becomes the material for eight hours to a heat aging temperature from about 180 to 200 ° C brought. After that lets Let it cool to room temperature.
Ein derartig hergestelltes Radialverdichterlaufrad hat nur eine begrenzte Wärmefestigkeit. Wenn die Austrittstemperatur der Luft die Wärmeauslagerungstemperatur für einige Zeit erreicht oder übersteigt, tritt am Außenrand des Laufrades, also im Bereich des Austritts der komprimierten Luft, eine Überalterung des Werkstoffs auf. Diese Überalterung bewirkt einen Festigkeitsabfall, wodurch Schäden hervorgerufen werden können, beispielsweise durch Ausbrechen von Teilen des Laufrades.One such manufactured radial compressor impeller has only a limited Heat resistance. If the outlet temperature of the air the heat aging temperature for some Time reaches or exceeds, occurs at the outer edge of the impeller, that is in the region of the exit of the compressed air, an aging of the material. This aging causes a drop in strength, which can cause damage, for example by breaking out parts of the impeller.
Der Erfindung liegt die Aufgabe zugrunde, ein Radialverdichterlaufrad eingangs genannter Gattung zu schaffen, das höheren thermischen Belastungen im Bereich des Austritts des zu komprimierenden Gases gewachsen ist.Of the Invention is based on the object, a radial compressor impeller initially mentioned genus to create the higher thermal loads grown in the region of the exit of the gas to be compressed is.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass der äußere Bereich des Laufrades unter Bildung eines Gradientenwerkstoffs mit dem Grundwerkstoff aus einem Zusatzwerkstoff besteht, der aus einer hochwarmfesten Al enthaltenden Legierung gebildet ist. Dadurch lässt sich ein Radialverdichterlaufrad ausreichender Festigkeit mit einem hochwarmfesten äußeren Bereich herstellen.According to the invention this Task solved by that the outer area of the impeller forming a gradient material with the base material consists of a filler material, which consists of a high-temperature resistant Al-containing alloy is formed. This can be done a radial compressor impeller of sufficient strength with a high temperature resistant outer region produce.
Gemäß einer ersten Variante der Erfindung besteht der Zusatzwerkstoff des äußeren Bereiches aus einer zumindest Al und C enthaltenden Legierung. Nach einer anderen Variante der Erfindung besteht der Zusatzwerkstoff des äußeren Bereiches aus einer zumindest Al und Fe enthaltenden Legierung.According to one first variant of the invention consists of the filler material of the outer region an alloy containing at least Al and C. After another Variant of the invention consists of the filler material of the outer region of an alloy containing at least Al and Fe.
Zur Herstellung eines Radialverdichterlaufrades der eingangs genannten Gattung wird aus dem pulvermetallurgisch vorliegenden Grundwerkstoff und Zusatzwerkstoff durch ein heißisostatisches Pressverfahren ein Rohling aus einem Gradientenwerkstoff hergestellt. Alternativ wird zum gleichen Zweck durch sprühkompaktieren des aufgeschmolzenen Grundwerkstoffs und des aufgeschmolzenen Zusatzwerkstoffes ein Rohling aus einem Gradientenwerkstoff hergestellt.to Production of a radial compressor impeller of the aforementioned Genus is from the powder metallurgical present base material and Additional material by a hot isostatic pressing process a blank made of a gradient material. alternative is for the same purpose by spray-compacting the melted Base material and the molten filler a blank made of a gradient material.

Beim zweiten Ausführungsbeispiel wird wiederum als Grundwerkstoff eine Al-Cu-Legierung verwendet, der weitere Bestandteile wie Mg in geringen Mengen zugesetzt sein können. Als Zusatzwerkstoff wird eine warmfeste, schnell erstarrende (rapid solidification) Legierung mit den Bestandteilen Al und Fe verwendet, der in geringen Mengen weitere Zusatzlegierungsbestandteile zugesetzt werden können.At the second embodiment In turn, the base material used is an Al-Cu alloy, which contains additional constituents as Mg may be added in small amounts. As a filler material is a heat-resistant, rapidly solidifying alloy used with the components Al and Fe, in small quantities other additional alloying ingredients can be added.
