The electrochemical impedance spectroscopy of silver doped hydroxyapatite coating in simulated body fluid used as corrosive agent
Titanium is a key biomedical material due its good biocompatibility, mechanical properties and corrosion stability, but infections of the implantation site still pose serious threat. One approach to prevent infection is to improve antimicrobial ability of the coating material. Silver doped hydro...

| description | Titanium is a key biomedical material due its good biocompatibility, mechanical properties and corrosion stability, but infections of the implantation site still pose serious threat. One approach to prevent infection is to improve antimicrobial ability of the coating material. Silver doped hydroxyapatite (Ag/HAP) nanoparticles were synthesized by new modified precipitation method. The synthesized powder was used for preparation of Ag/HAP coating on titanium by electrophoretic deposition. The coating was characterized in terms of phase composition and structure by Attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) and X-ray diffraction (XRD); surface morphology and chemical composition was assessed using scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). Research focused on evaluation of the corrosion behaviour of Ag/HAP coating in simulated body fluid (SBF) at 37 ºC during prolonged immersion time by electrochemical impedance spectroscopy (EIS). Silver doped HAP coating provided good corrosion protection in SBF solution. [Acknowledgements.
