Plasma electrolytic oxidation (PEO) is a promising surface treatment for generating thick, adherent coating on valve metals using an environmentally friendly alkaline electrolyte. In this study, the PEO method was used to modify of AZ31 Mg alloy. The composite coatings were formed in phosphate-based electrolyte containing hydroxyapatite nanoparticles (NPs) and different concentrations (1, 2, 3, 4 g/L) TiO2 NPs. results showed that incorporation NPs increased porosity, thickness, roughness, wettability coatings. corrosion-resistance simulated body fluid (SBF) tested up 72 h all superior corrosion resistance compared bare substrate. Among samples TiO2, sample 1 g/L had highest inner layer (0.51 kΩ·cm2) outer (285 lowest average friction coefficient (395.5), so it best wear performance. antibacterial tests higher concentration NPs, lower adhesion bacteria, resulting enhanced properties against S. aureus. addition provided rate 97.65% coating.
