Abstract
Antibacterial coatings were formed on Mg alloy by plasma electrolytic oxidation (PEO) with subsequent antibiotic impregnation. Morphological features and composition of formed layers were studied by SEM and EDS. Corrosion current density of formed coatings substantially decreased compared to bare alloy. Incorporation of Vancomycin did not lead to a decrease in the electrochemical properties. The antibacterial activity of the coatings against S. aureus and methicillin-resistant S. aureus was investigated in vitro model. It was established that for antibacterial coatings the number of colony-forming units significantly decreased compared to both base PEO-coating and bare alloy.
