Surface coating of titanium (Ti) and its alloys with bioceramic materials is one of the main surface modification techniques used for developing different properties required for biomedical applications like mechanical strength, biocompatibility and corrosion behavior. In this work, pure HA and composite HA/TiO 2 bioceramic coatings were prepared and deposited successfully on the surface of new biomedical Ti-Zr-Nb alloy system by sol-gel method. In order to investigate the surface properties of uncoated and coated substrates, various surface examinations were made such as surface topography, thickness, morphology and phase transformations. Furthermore, wear and corrosion properties of uncoated and coated substrates were also evaluated. The results displayed that the composite HA/TiO 2 film can be considered as a potential thin film favorable for hard tissue application as it possesses an advanced crystallization and homogeneous nano-scale structure with outstanding wear and corrosion properties.
