Abstract
Biodegradable Zn-0.4Li alloys have been considered as medical implants due to their excellent mechanical properties and desirable biocompatibility. In this work, anodization was applied to modified corrosion resistance of the Zn-0.4Li alloy by forming a uniform and neat flower-like nanowire coating on the surface. After anodization for 7 min, the anodized Zn-0.4Li alloy had a yield strength of 253.6 MPa, ultimate tensile strength of 389.5 MPa, and elongation at a break of 66.0%. The corrosion rate of the Zn-0.4Li-7 min sample reached 0.5741 mm/y in the SBF, which was almost 18 times higher than that of the Zn-0.4Li alloy. The anodized Zn-0.4Li alloy exhibited higher antibacterial properties than that of the Zn-0.4Li alloy against Escherichia coli and Staphylococcus aureus. These results suggested that anodization may be an effective method to modulate the corrosion behavior of zinc alloys, which can be applied in the surface modification of biodegradable implants.
