Abstract

Magnesium (Mg) alloy is a novel biomedical material for medical implants due to its biodegradability and high biocompatibility. Manganese (Mn) is added to this alloy to enhance its corrosion resistance, given Mg’s low corrosion resistance, while copper (Cu) contributes antibacterial properties. This study investigates the potential of Mg-Mn-Cu alloy as a biodegradable material for biomedical implants. The alloy’s enhanced corrosion resistance and antibacterial properties were evaluated through high-energy ball milling, sintering, and antibacterial testing. The findings suggest that the Mg-Mn-Cu alloy is a promising biodegradable material due to its mechanical properties and biodegradability. Mg-Mn-Cu alloy shows potential as a novel material for medical implants due to its high strength, corrosion resistance, and biocompatibility. Mn forms a solid solution or precipitates as fine MgMn (or elemental Mn) particles. It acts as the primary stabilising agent to counteract the high corrosion of Mg in the alloy. Cu is highly valued for its long-lasting, broad-spectrum antimicrobial properties. As the implant slowly dissolves in the body, the Mg₂Cu phase continuously releases trace amounts of Cu2+ ions, which disrupt bacterial cell membranes and effectively prevent implant-associated infections.
