title = "Effect of 2 wt% Ag Addition on Corrosion Properties of ZK40 for Biodegradable Applications",
abstract = "The antibacterial effects of silver make it an attractive alloying element for biodegradable Mg alloys to treat possible inflammation and infections caused by the degrading orthopedic implants. In this study, as-extruded Mg–4%Zn–0.5%Zr (ZK40) alloy was alloyed with Ag, specifically 2 wt%, and subjected to a heat treatment at 350 ℃ for 7 days. The mechanical and corrosion responses were studied in two orthogonal planes (transverse and extrusion) before and after silver addition to explore its potential for biodegradable orthopedic applications. Corrosion characteristics were assessed at 37 ℃ in Hank{\textquoteright}s solution for 24 h via electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PD) and open circuit potential (OCP). As-extruded and heat-treated ZK40 alloy displayed an inhomogeneous microstructure containing large, coarse grains, Zn–Zr rich secondary phase and some fine grain regions. While in ZK40–Ag, both planes showed a relatively more homogenous microstructure but with some agglomeration of Zn–Ag rich secondary phases. Here, we present our initial results on the different corrosion behaviors observed in the two materials.",
