| Abstract: | Superhydrophobic TiO2 nanotube arrays on pure Ti was prepared by surface-modification in Hexamethyldisilazane (HMDS) solution and its performance, surface morphology and composition were characterized by means of water contact angle measurement, energy dispersive X-ray spectrum (EDS) and scanning electron microscopy (SEM). The corrosion behavior of the superhydrophobic surface film was investigated with potentiodynamic polarization measurements and electrochemical impedance spectroscopy(EIS). The results showed that the superhydrophobic surface film significantly decreased the corrosion currents densities (Icorr), increased the polarization resistance (Rt) of Ti. Due to the air valleys and capillarity effects, the corrosion resistance of the material was improved remarkably. |
