Reinforcing bone repair in osteoporosis: nanocomposite-embedded AZ31 MG alloy screws for improved resilience and strength

The research focuses on the application of nanocomposite coatings to enhance the characteristics of AZ31 Mg alloy for use in orthopedic implants application. Titanium-zirconium (Ti-Zr) nanocomposites were employed to enhance the osteointegration, abrasion resistance, controlled degradation, strength, and durability of the AZ31 alloy. Surface analysis confirmed the successful adhesion of the Ti-Zr coating to the AZ31 magnesium alloy screw. Improved mechanical strength was observed in the Ti-Zr coated screws compared to the uncoated ones, as evidenced by ultimate tensile strength (UTS) analysis. Corrosion studies revealed enhanced corrosion resistance in the coated implants. The research examines the application of nanocomposite coatings to enhance the characteristics of AZ31 Mg alloy for use in orthopedic screw implants. Additionally, contact angle measurements indicated controlled degradation properties. In vitro studies demonstrated significantly improved osteointegration with prolonged treatment periods, highlighting the promising biological potential of these nanocomposite-coated implants. Overall, this work demonstrates the ability of nanocomposites to enhance implant materials, potentially reducing postoperative complications and paving the way for a reliable material for orthopedic applications.
