Abstract

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 these biodegradable zinc-based alloys through a unique combination of alloy design and advanced processing techniques. The goal is to address the key limitations of conventional zinc-based biomaterials. The research focuses on the application of melt spinning followed by hot extrusion to produce Zn–4.1Ag–0.7Cu–0.4Mn–0.03 Mg alloys. These alloys feature fine-grained, homogeneous microstructures that exhibit superior mechanical properties and enhanced corrosion uniformity. Specifically, the melt-spun alloy demonstrates an increase in ductility (approximately 16%) while maintaining a high tensile strength of around 416 MPa. It also shows reduced corrosion rates and more uniform degradation compared to its cast counterpart. Achieving this combination of properties in zinc-based alloys marks a significant advancement for biodegradable cardiovascular stent applications.
