ObjectivesThe aim of the present study was to investigate the effect of thermal oxidation on the corrosion behavior of Ti–5Ag alloy.MethodsThe microstructure of Ti–5Ag alloy without and with thermal oxidization treatment were characterized, with commercial pure (CP) Ti as control, by means of X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). The electrochemical behavior in artificial saliva solution was compared for CP Ti, Ti–5Ag alloy with and without thermal oxidation.ResultsCompared to CP Ti, Ti–5Ag alloy without thermal oxidization treatment possessed much lower current density, higher open circuit potential, larger impedance value, and its corrosion resistance could be further improved with thermal oxidation.SignificanceThe corrosion resistance was enhanced by Ag addition for titanium and could be further improved by thermal oxidation.
