    The metallic implants are used in various medical areas such as screws, plates, pins or others. Titanium alloys are the most popular implant materials for many years due to their higher strength and biocompatibility and excellent corrosion resistance. However, they need a bioactive layer on their surfaces for improve osseointegration with bone surroundings. In this study, the hydroxyapatite/titania (HA/TiO2) bioactive coatings has been syntheses on Ti-6Al-4V substrates by sol-gel method, successfully. The effect of TiO2 reinforcement to the HA structure was evaluated by using X-ray diffraction (XRD), scanning electron microscopy (SEM) and corrosion tests. The electrochemical susceptibilities of the coatings have been determined under in-vitro conditions by potentiodynamic polarization scanning (PDS) technique. The result showed that the coating structure has porous morphology as cauliflower. In addition, the PDS curves of coated and uncoated specimens show a passive behaviour and the coated sample has higher corrosion resistance than uncoated Ti-6Al-4V sample against the Ringer solution. © 2017 WILEY-VCH Verlag GmbH & Co.
