摘      要：The microstructural observation,the mass loss test,potentiodynamic polarization measurements and corrosion morphology examinations were conducted to study the influence of microstructural characteristics on corrosion behavior of Mg–5Sn–3In alloys in Hank’s solution after *** results show that the corrosion rate of the as-cast alloy is similar to that of as-extruded alloy;however,the local corrosion susceptibility is greatly weakened in the as-extruded alloy,especially in the extrusion *** relatively uniform corrosion morphology of the as-extruded alloy is attributed to refined Mg_(2)Sn particles,uniform distribution of Mg_(2)Sn particles and favorable crystal ***,the cytotoxicity tests confirm that the Mg–5Sn–3In alloy exhibits cytotoxicity of Grade 0−1 for NIH3T3 cells,suggesting an acceptable cytotoxicity of this alloy in the vitro assay.
