摘要: Abstract The mechanical properties and bio-corrosion behaviors of as-extruded Mg–4Zn alloys after Sn addition were investigated, systematically. A small amount to alloy slightly improved the for solid solution strengthening, significantly controlled rates. participating in outer layer film formation as SnO/SnO2 resisted proceeding. Especially, Mg–4Zn–1.5Sn alloy, with a weight loss rate 0.45 mm/y hydrogen evolution 0.099 mL/cm2/day, showed cytotoxicity grade 0 MC3T3-E1 cells. perfect alliance cytocompatibility, suitable low demonstrates that this is promising biodegradable magnesium orthopedic implants.
