Dual alloying improves the corrosion resistance of biodegradable Mg alloys prepared by selective laser melting

Mg alloys have been regarded as revolutionary metallic biomaterials for biodegradable bone implants, but their applications are mainly blocked by the too rapid degradation in physiological environment. This study explores the dual alloying effects of Mn and/or Sn on the performance of Mg alloys prepared by selective laser melting. The observed microstructure indicated remarkable refinement of both the grains and intermetallic phases in the Mn-...
