A titanium-based alloy with applications as implantable material was chemically graved through different methods, in order to improve the adhesion of a thin hydroxyapatite (HA) film. The aim of this study is to increase the biocompatibility of a metallic material by deposition of a ceramic material on his surface. The metallic material, known as titanium Grade 5 (Ti6Al4V), was investigated through Scanning Electron Microscopy (SEM, with a SE detector for 2 and 3D images) and an Energy Dispersive X-ray Analyser (EDAX), after chemical attack and after HA deposition. Hydroxyapatite was deposited using electrophoretic equipment, each time using the same experimental conditions, so that a comparison can be made. After deposition, the material was calcined and some mechanical properties were investigated. The experimental results present a homogeneous layer formed with a very good adhesion and dimensionally reduced particles. The metallic material, used as dental implant, presents a better corrosion resistance in simulated body fluid electrolyte and the EIS (Electrochemical Impedance Spectroscopy) tests emphasize the formation of two layers, a compact one of TiO2 (titanium oxide) and a porous one of HA on top of the surface.
