Selektives Elektronenstrahlschmelzen von speziellen Legierungen

   Es wird das Potential schwierig zu verarbeitender Legierungssysteme für die Prozessierung mittels SEBM eruiert. Dazu gehören z.B. eigentlich nicht schweißbare Nickelbasislegierungen oder spezielle Kupferlegierungen. Es bestehen aber auch Erfahrungen in der Verarbeitung von Titanlegierungen, insbesondere für medizinische Anwendungen, Titanaluminiden und Stählen.
   Es werden die materialwissenschaftlichen und reaktionstechnischen Grundlagen zur simultanen Erzeugung von Trägermaterial und katalytischer Funktion strukturierter Reaktoren aus Raney-Cu mittels SEBM erforscht. Der aktive Katalysator wird dabei aus der SEBM-gefertigten Struktur durch Auslaugung erzeugt, so dass geometrische Restriktionen der aufwändigen Beschichtungsverfahren zur katalytischen Funktionalisierung wegfallen.
