  • BSc, (2012-2016): Evaluation of the wear properties of Bioglass-chitosan/anodized Ti implant

Abstract:

In the present work, we studied the effects of titania nanotube formation incorporated with chitosan bioactive glass on electrochemical behavior of titanium substrates. The samples were characterized by Scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FR-IR). The corrosion behavior of coated samples was investigated in Ringer solution through potentiodynamic polarization and electrochemical impedance spectroscopy measurements. The results showed that the TiO2 nanotubes orderly formed on titanium substrate through electrochemical anodizing process and variation in the applied voltage and duration of anodizing process resulted in formation of TiO2 nanotubes with various diameters. In addition, the corrosion results showed that the formation of titania nanotubes and chitosan-bioactive glass on Ti substrate improved the corrosion behavior of titanium substrate. In addition, our study revealed a rise in hardness of treated samples compared to untreated ones and good adhesion strength to the substrates. These good mechanical and electrochemical characteristics make the nanohybrid TiO2 nanotube/chitosan-Bioglass coating, a proper candidate for dental applications.
