Selectiv electron beam melting of special alloys

   We examine the possibility to process high performance alloys such as non-weldable Nickel-base alloys or special Copper alloys by means of SEBM. There are also experiences in the processing of Titanium alloys, in particular for medical applications, Titanium aluminides and steels.
   We also study the fundamentals of material science and reaction technology for the simultaneous production of carrier material and catalytic function of structured reactors made by SEBM. The active catalyst (Raney copper type) develops from the AM manufactured structure by leaching. Thus, geometric restrictions of complex coating processes for catalytic functionalization disappear. The direct generation of the catalytically active material on the carrier structure is expected to show advantages with respect to thermal management.
