Abstract

By means of surface mechanical attrition treatment (SMAT), a nanocrystalline surface layer was formed on a Ti–6Al–4V alloy. The corrosion behavior of Ti–6Al–4V in a Ringer's solution was investigated by potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS) measurements. Overall results of all studies identified beneficial impacts of SMAT on corrosion behavior of Ti–6Al–4V alloy. The surface oxide film formed on Ti–6Al–4V and its stability in biological environments play a decisive role for the biocompatibility of implants. In this study, passive oxide films formed on Ti–6Al–4V surfaces and their natural growth in a Ringer's solution have been investigated by microhardness and X-ray photoelectron spectroscopy (XPS).
