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
(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 (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 (SEM), the elementary analyses namely Energy Dispersive X-ray
Spectroscopy (EDS) for the surfaces of coating have been determined and X-Ray
Diffraction (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.
