Abstract:

The effect of addition of (2-methoxy 4-allyl phenol), eugenol, on the corrosion of Titanium-Nickel (TiNi) in physiological media was investigated through electrochemical impedance spectroscopy (EIS), free potential, potentiodynamic polarization curves and gravimetric measurements. The obtained results showed that eugenol revealed a good corrosion inhibitor. The inhibition efficiency depends on both the nature of treatment and concentrations of eugenol. Scanning electron microscopy (SEM) of the TiNi revealed that eugenol is adsorbed on the surface of TiNi.

Keywords:

eugenol, corrosion, inhibitor, electrochemical method, physiological media.
