EFFECT OF THERMAL OXIDATION ON THE CORROSION RESISTANCE OF CP-Ti

Abstract

<p class="AMSmaintext">Commercially pure titanium (CP-Ti) was subjected to thermal oxidation at different temperatures and times for determining the optimum oxidation conditions to obtain the optimum corrosion resistance. The phase constituents of the samples were determined by X-ray diffraction (XRD), the morphology of the surface was observed by SEM, and the corrosion behavior was investigated using immersion test by exposing the samples in HCl solutions with a concentration of 37%. The results showed that Rutile TiO<sub>2</sub> layer was formed on the surface of CP-Ti after thermal oxidation and the thickness of the TiO<sub>2</sub> layer increased with the treating temperature. Meanwhile, It was found that the optimum corrosion resistance to HCl was obtained while oxidizing at 700℃ for 330min～500min.</p>

Influence of Isothermal Oxidation on Corrosion Resistance of Titanium in Bovine Serum

“…This has been stimulating the research on titanium surface modification to improve the wear and corrosion resistance. Thermal oxidation treatment has been used as one of the popular methods for the surface treating of titanium material [7], [11], [12]. Due to this treatment produces a combination of a good of surface properties and enhance the biocompatibility of titanium [7], [13].…”
