Abstract

Magnesium has been considered as a new biodegradable material for orthopaedic applications because of its prominent properties including superior biocompatibility, biodegradability, and proper mechanical stiffness. For the direct production of custom biomedical implants, direct laser deposition (DLD) has been applied to fabricate bulk pure magnesium and its resultant properties were studied. Surface morphology, microstructure and mechanical properties of DLD specimen were investigated. The relative porosity of DLD specimen was equal to about 6 %. The microhardness and elasticity modulus of the DLD bulk magnesium were equal to (0.49 ± 0.09) GPa and (30 ± 4) GPa, respectively.
