The in-vitro degradation and in-vitro cytotoxicity of the as-extruded Mg-4.0Zn-0.2Ca alloy were investigated.The in-vitro corrosion tests indicate that Zn and Ca elements can dramatically increase the corrosion potential of the as-extruded Mg-4.0Zn-0.2Ca alloy in the simulated body fluid and reduce the degradation rate.The cytotoxicity of the as-extruded Mg-4.0Zn-0.2Ca alloy examined by MTT tests on L929 cells suggest that the alloy has eligible toxicity for implant applications.
