Abstract In this research, Plasma Electrolytic Oxidation technique was used to incorporate ZnO–ZrO2 nanoparticles into TiO2 ceramic coating on Ti6–Al–4V using sodium phosphate as the electrolyte. The effect of adding these nanoparticles on corrosion, morphology, wettability and antibacterial properties in the simulated body fluid (SBF) solution was investigated. The results indicated nanoparticles modified the microstructure of coating, which increased corrosion resistance 12 times higher than that of substrate. Besides, ZrO2 nanoparticles had the most significant effect on increasing the contact angle. In addition, due to the compatibility of zirconium and zinc oxides with human body environment, the antibacterial properties of coatings were significantly improved.
