Abstract
In this paper, nanostructured silver-doped zinc oxide (Ag-ZnO) coating was prepared on Mg-2Ca-0.5Mn-6Zn alloy surface with improved corrosion resistance and antibacterial activity through physical vapor deposition (PVD). Microstructural analysis showed that the Ag-ZnO coating was adherent to the substrate with a thickness and particle size of 1 µm and 85 nm, respectively. The nanostructured Ag-ZnO coated specimens exhibited lower corrosion current density (icorr), and higher charge-transfer resistance (Rct) compared with the uncoated Mg alloy. Antimicrobial examination demonstrated that the Ag-ZnO coated specimen revealed a significantly better antimicrobial performance toward Escherichia coli and Staphylococcus aureus compared to the uncoated sample. The results also showed that the Ag-ZnO coating considerably reduces the corrosion rate and improves antimicrobial performance of the Mg alloy substrate.
