Abstract

A new surface modification protocol encompassing an anodization treatment has been developed to improve the surface properties of biomedical titanium. Anodization in presence of nickel sulfate is one of a good way to improve the resistance of commercial pure titanium (cp‐Ti) in phosphate saline buffer solution (PSB). The potentiostatic behavior of anodized titanium in sulfuric acid with nickel sulfate differed markedly from that of titanium anodized in sulfuric acid free from nickel sulfate. Polarization and electrochemical impedance spectroscopy (EIS) recorded an increase in the corrosion resistance of the passive film. Scanning electron microscopy (SEM) and energy diffraction X‐ray (EDX) analysis were used to investigate the morphology and structure of the anodized film in absence and in presence of nickel sulfate. On the other hand, sealed anodized titanium samples exposed to PSB for up to 3 days have been studied by EIS to obtain detailed information concerning the electrochemical properties of sealed anodized titanium. An equivalent circuit that reproduces the impedance results of porous cp‐Ti oxide (TiO~2~) films is proposed. These observations indicate that anodization of cp‐Ti in presence of nickel sulfate and sealing the anodized film can serve as a simple low‐temperature method to enhance the corrosion resistance of cp‐Ti when used as an implant material.

Titanium is widely used in dental implantology and orthopaedics due to its excellent corrosion resistance and mechanical properties. However, it has been reported that Ti is sensitive to F ¡ , H 2 O 2 and lactic acid. Atomic force microscopy (AFM) and scanning electron microscopy (SEM) were used to
