Abstract Scope |
Zinc and zinc alloys as biodegradable metals have been investigated widely for orthopedic and vascular stents due to its ideal bio-corrosion behavior and biocompatibility. Alloying zinc with other elements often results in a compromise in ductility. Here, WC nanoparticles were introduced to the Zn-Fe alloy system aiming to providing additional strengthening and microstructure modification to retain ductility. Thermally stable WC nanoparticles refined the primary grains and modified the FeZn13 precipitate morphology and significantly. Consequently, WC nanoparticles simultaneously enhance the mechanical strength and ductility while maintaining the good corrosion rate and biocompatibility. Overall, this novel Zn-Fe-WC nanocomposite could be potentially applied as a biodegradable material for widespread biomedical applications. |
