Selective laser sintered porous Ti-(4-10)Mo alloys for biomedical applications: Structural characteristics, mechanical properties and corrosion behaviour

摘要

Porous Ti-(4-10)Mo alloys (4, 6, 8 and 10 wt.% Mo) were prepared from elemental metallic powders by indirect selective laser sintering. This investigation focuses on porous, microstructural, mechanical and electrochemical properties to clarify their interrelation. The results demonstrated that lower porosity level and higher 13 content are beneficial to improved mechanical behaviour, while smaller pore size and lower porosity to better corrosion resistance. Namely, structural characteristics influence mechanical properties, whereas electrochemical behaviour is dominated mainly by porous features. The unique porous structure combined with suitable mechanical properties and high corrosion resistance make porous Ti-Mo alloys prospective biomaterials for orthopedic implants.
