| Abstract Scope |
Zinc-based alloys are promising biodegradable materials for biomedical applications due to their biocompatibility and lower corrosion rates compared to magnesium alloys. This study explores a novel approach to developing biodegradable zinc-based alloys through a unique combination of alloy design and advanced processing techniques, aimed at addressing the main limitations of conventional zinc-based biomaterials. The research focuses on the application of melt spinning followed by hot extrusion, which allows for the production of Zn-4.0Ag-0.8Cu-0.6Mn-0.05Mg alloys. These alloys feature fine-grained and homogeneous microstructures that display superior mechanical properties and improved corrosion uniformity. The melt-spun alloy shows a remarkable increase in ductility (~16%) while maintaining high strength (ultimate tensile strength of ~416 MPa), along with reduced corrosion rates and more uniform degradation compared to its cast counterpart. Achieving this level of property synergy in zinc-based alloys marks a significant advancement for biodegradable applications. |
