Electrochemical and interface analysis of titanium alloy in simulated body fluid

Abstract

The effect of raftiline inulin in presence of Ca 2+ on titanium alloy as biomaterial was investigated in simulated body fluid solution at 37°C. The behavior of Ti alloy was studied at different concentrations of inulin with immersion time using electrochemical impedance spectroscopy and potentiodynamic polarization tests. Ti alloy was effectively inhibited by the addition of 0.25% by weight raftiline in presence of 10 À5 M calcium levulinate, which reacts with Ti alloy and forms a protective film on its surface. The results were confirmed by surface examination via scanning electron microscope.

Effect of fluoride and hydroxyl group on bioactivity of the anodized films prepared by two‐step anodization at low current density

“…Titanium and its alloys are promising dental implant materials 1–7 due to their good mechanical properties, corrosion resistance, and good biocompatibility 8–28 . However, the causes of implantation failure are that their biological inertia results in the difficulty to directly join with the human bond tissue 29 and a poor ability to facilitate new tissue formation at the early stage of implantation.…”

Effect of Fumed Silica/Chitosan/Poly(vinylpyrrolidone) Composite Coating on the Electrochemical Corrosion Resistance of Ti–6Al–4V Alloy in Artificial Saliva Solution

“…Titanium alloys have great applications in implantology, such as dental, orthopedic prostheses owing to their own high mechanical properties, great corrosion prevention, and outstanding biocompatibility in biofluids. The superb corrosion resistance of titanium and its alloys in biological solutions is attributed to the formation of the high stable and protective titanium dioxide film on the surface. − …”
