  Abstract:  The aim of this work was to study the effect of electrochemical and electrophoretic deposition of hydroxyapatite (HA) on commercial pure titanium substrates, regarding the corrosion behaviour of the coated biomaterials during their preservation in physiological media. The coated surfaces were analyzed by X-Ray Diffraction and Scanning Electron Microscopy. The degradation characteristics of HA coated on the Titanium implants was investigated as a function of immersion time in Ringer solution, using the Electrochemical Impedance Spectroscopy (EIS) technique. A double-layer model of the coated film was found; a compact protective inner layer and a porous external layer with open or sealed pores, as a function of immersion period.
