Abstract

Bei einem Verfahren zur Herstellung von Metallschäumen mit stabilisierenden Teilchen in der Metallmatrix, mit mindestens den Verfahrensschritten Herstellen eines schäumbaren Ausgangsstoffes und Aufschäumen dieses Ausgangsstoffes, werden erfindungsgemäß die stabilisierenden Teilchen bei der Herstellung des schäumbaren Ausgangsstoffes in einer in situ-Reaktion von geschmolzenen reaktiven Flüssigkeiten und einer Metallschmelze erzeugt, wobei der Metallschmelze die Bestandteile der zu erzeugenden submikroskopischen Partikel oder Nanopartikel mindestens als Fluoridsalz hinzugegeben, anschließend gemischt und über die Schmelztemperatur der Mischungsbestandteile erhitzt werden. Mit dem Verfahren lassen sich Metallschäume herstellen, die stabilisierende Teilchen in einer Metallmatrix enthalten, wobei die stabilisierenden Teilchen weniger als 10 vol.% in der Metallmatrix enthalten sind, eine Größe kleiner 1 μm aufweisen und in einem Kontaktwinkel von 10 bis 100° angeordnet sind, und die Metallmatrix gebildet ist aus gleichmäßig angeordneten polygonalen geschlossenen Zellen mit einem durchschnittlichen Durchmesser von 2 bis 10 mm und der Metallschaum eine Porosität von mindestens 75 % aufweist.
