AB - A novel nano-composite film coat of organic/inorganic composition including chitosan (CS), TiO2 nanoparticles (TO) and hydroxyapatite (HA) nanoparticles, was synthesized on a Ti–6Al–4V alloy surface. Open-circuit potential (OCP), electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization measurements were used to observe the corrosion behavior of the novel synthesized nano-composite coat on titanium alloy surface in a phosphate buffer solution. The results were confirmed by scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) analysis techniques. The antibacterial activity for the novel nano-coat was determined and compared with the bare Ti alloy. Electrochemical impedance spectroscopy measurements showed that the total corrosion resistance of this newly synthesized nano-coat gave the highest corrosion resistance compared to the separate CS, TO and/or HA coatings. Also, this novel nano-coat showed high antibacterial activity compared with the bare alloy. The excellent biocompatibility of this novel nano-coat may be due to its organic/inorganic composition.
