Abstract

Freestanding scaffolds were fabricated of Mg5W (wt.% yttrium) alloy using magnetron sputtering technology. Appropriate method was found to produce scaffolds with high reproducibility, spatial resolution of 1 μm and good mechanical properties. Two different techniques were used for surface finishing, microblasting and chemical polishing. SEM investigation showed high surface quality after chemical polishing while microblasting influenced mechanical properties of the Mg5W alloy. Magnetron sputtering offers a high potential for the production of microstructured scaffolds.
