“…The broad bands at 3440 and 3454 cm À1 due to adsorbed H 2 O in the material were observed. Similar results were reported for the FT-IR analysis of apatite (Ref [15][16][17]. From the above observations, it could be confirmed that a layer of apatite forms on the surface of b-Ti alloy after immersion in SBF solution.…”

Ti-15Mo (b-Ti) alloy was subjected to chemical followed by thermal treatment for the enhancement of in vitro bioactivity and corrosion resistance. The surface-modified specimens were characterized using scanning electron microscopy (SEM) and energy dispersive x-ray analysis (EDAX). The results indicated the formation of nanoporous layer and flake-like structure developed during chemical and subsequent thermal treatments. The in vitro bioactivity of the surface-treated b-Ti alloy was evaluated by immersing in simulated body fluid (SBF) solution. The formation of apatite particles was confirmed using Fourier transform-infrared spectroscopy, SEM, and EDAX analyses. Moreover, the electrochemical behavior of surface-modified specimens in SBF solution was evaluated using potentiodynamic polarization and electrochemical impedance spectroscopy. The results revealed that the surface-modified specimens exhibited higher potential value and lower current density when compared to untreated specimen. The EIS studies showed the formation of new layer, indicating the growth of apatite-like particles.

“…The broad bands at 3,448 cm -1 due to adsorbed H 2 O in the material and two broad bands at 2,369 and 2,345 cm -1 for soluble CO 2 were also observed. Similar results were reported for the FT-IR analysis of apatite [26][27][28]. From the above observations, it could be confirmed that a layer of apatite forms after immersion in Hanks solution [29].…”

The passive film behavior of Ti-6Al-4V ELI (Extra Low Interstitial) alloy after a chemical treatment followed by a thermal treatment was morphologically and electrochemically characterized. The surface morphological studies were carried out using scanning electron microscopy (SEM), electron dispersive X-ray analysis (EDAX), and Fourier Transformed-Infra Red (FT-IR) analysis to investigate the nucleation and growth of apatite on the chemically and thermally treated Ti-6Al-4V ELI alloy immersed for different durations in Hanks solution. Polarization and impedance spectroscopic (EIS) measurements were carried out in Hanks solution and the electrical parameters were obtained for the passive film using a nonlinear least square fitting (NLLS) method.
