Abstract
Die Erfindung betrifft ein Verfahren zum Herstellen einer Wabendichtung durch pulvermetallurgisches Spitzgießen, wobei beim pulvermetallurgischen Spitzgießen zuerst ein Metallpulver und/oder ein Keramikpulver mit zumindest einem Bindemittel zu einer homogenen Masse vermischt wird, wobei anschließend aus der homogenen Masse durch Spritzgießen ein wabenartige Zellen aufweisender Formkörper für die Wabendichtung gefertigt wird, wobei der Formkörper darauffolgend einem Entbinderungsprozess unterzogen wird, und wobei im Anschluss durch Sintern der Formkörper zu der Wabendichtung mit gewünschten geometrischen Eigenschaften verdichtet wird. Erfindungsgemäß werden vor dem Sintern zumindest einige der Zellen des Formkörpers zumindest teilweise mit jeweils mindestens einem Hohlkörper befüllt, wobei anschließend der Formkörper zusammen mit den in die Zellen eingeführten Hohlkörpern gesintert wird.
