DED and laser cladding of titanium alloys and nickel superalloys for aerospace
Christoph Leyens is Professor at TU Dresden and Director of the Fraunhofer Institute for Material and Beam Technology (IWS) in Dresden, positions he has held since 2006. His research focuses on directed energy deposition and laser cladding of high-temperature alloys — in particular titanium aluminides (TiAl) and nickel-based superalloys destined for aircraft turbine blades and structural aerospace components. He has been a principal contributor to laser DED repair strategies for turbine airfoils, demonstrating that DED-repaired TiAl blades can recover mechanical properties to within 5% of wrought equivalents. Leyens co-edited the reference volume "Titanium and Titanium Alloys" (Wiley-VCH) and has led several EU-funded projects on qualification of AM aero-engine parts, including participation in Clean Sky 2 and TAKE-OFF programmes. He has been active in metal AM research since approximately 2003.
