Abstract :The use of implant materials is one of the important surgical interventions in the treatment of disorders that are congenital and acquired deformities in musculoskeletal system. Metallic biomaterials within these implant materials are often preferred because of their proximity to the mechanical properties of the bone. In the implantation process, the surfaces of these alloys are coated with ceramic based biomaterials to increase the bioactivity and biocompatibility properties. In this study, it is aimed to create hydroxyapatite insert ignore into journalissuearticles values(HA); coating that is completely harmonious with human blood plasma environment, on Ti6Al4V alloy, using glycolic acid - sodium gluconate buffer system with biomimetic method for the first time in literature. Coating was realised inside synthetic body fluid insert ignore into journalissuearticles values(SBF); with waiting periods of 24, 48, 72 and 96 hours. Relating to the coatings, surface smoothness and thickness specifications have been determined, their micro structure has been analysed by Scanning Electron Microscope insert ignore into journalissuearticles values(SEM);, the elementary analyses namely Energy Dispersive X-ray Spectroscopy insert ignore into journalissuearticles values(EDS); for the surfaces of coating have been determined and X-Ray Diffraction insert ignore into journalissuearticles values(XRD); analysis have been conducted for obtaining the concentrations of the phases. As a result of the experiments, successful surface smoothness values and ratio of Ca/P close to optimal value have been obtained. Additionally, the presence of HA crystals with intense phase structure, with compact and homogeneous distribution on the substrate have been observed.
