In this study, calcium titanate (CaTiO3) gel was prepared by mixing calcium nitrate and titanium isopropoxide in 2-methoxy-ethanol. CaTiO3 gel was single-layer coated on Ti-6Al-4V using a sol-gel dip-coating technique. The coating was calcined at 750˚C in air by utilizing a very slow heating rate of 2˚C/min. The crystalline phases of the coating were characterized by x-ray diffraction using a slow scan rate of 1˚/min. The morphology of the coating was analyzed by scanning electron microscopy. The corrosion behavior of Ti-6Al-4V samples coated with CaTiO3 films were tested in an artificial saliva solution by potentiodynamic polarization and were quantified by the Tafel extrapolation method. The electrochemical parameters showed a considerable increase in the corrosion resistance for the CaTiO3-coated Ti-6Al-4V samples compared to bare substrates.
