Synthesis of Magnesium-Based Alloys by Mechanical Alloying for Implant Applications

The biocompatibility and biodegradability of magnesium (Mg), along with its lightness, make magnesium-based materials promising for use in the biomedical industry. In this work, ternary Mg–Zn–Ca alloys were manufactured applications using mechanical alloying (MA). objective work was to study effect milling time on produced Mg65–Zn30–Ca5 Mg70–Zn25–Ca5 (percentages by weight), degradation synthetic human fluids, their generated cytotoxicity. Mg-based synthesized a planetary ball mill under an argon atmosphere stainless-steel containers balls regimen 400 rpm 2, 5, 10, 15, 20 h. powders obtained after MA characterized scanning electron microscopy (SEM) X-ray diffraction (XRD), which verified that can be MA. XRD refinement analysis samples showed presence MgZn intermetallic phase. Electrochemical tests corrosion resistance current density improved compared those pure Mg. Cytotoxicity testing conducted Sulforhodamine B (SRB) assay, revealed did not exhibit cytotoxicity toward fibroblast cells. show good potential used applications.
