Abstract

Das Verfahren zur Herstellung von hochporösen, metallischen Formkörpern umfasst die folgenden Verfahrensschritte: ein als Ausgangsmaterial verwendetes Metallpulver wird mit einem Platzhalter vermischt, aus der Mischung wird ein Grünkörper gepresst, der Grünkörper wird einer konventionellen mechanischen Bearbeitung unterzogen, wobei der Platzhalter vorteilhaft die Stabilität des Grünkörpers erhöht, das Platzhaltermaterial wird an Luft oder unter Vakuum oder unter Schutzgas thermisch dem Grünkörper entfernt, der Grünkörper wird zum Formkörper gesintert und anschließend vorteilhaft trovalisiert oder gleitgeschliffen. Geeignete Materialien als Platzhalter sind beispielsweise Ammoniumbikarbonat oder auch Carbamid. Die mechanische Bearbeitung vor dem Sintern ermöglicht vorteilhaft eine einfache, endkonturnahe Herstellung auch für komplizierte Geometrien des herzustellenden Formkörpers, ohne die Porosität zu beeinträchtigen, und ohne hohen Werkzeugverschleiß. Das Werkstück ist vorteilhaft für die Grünbearbeitung ausreichend druckstabil, da das Platzhaltermaterial während der Bearbeitung noch in den Poren des Grünkörpers vorhanden ist.
