The electrochemical behavior of titanium has been investigated in chloride electrolyte of different pH values (2.1, 5.2 and 7.4). Potentiodynamic polarization studies showed wide passive behaviour irrespective of change in pH. Passive films were grown by applying different passive potentials (0.2 to 0.6n -type semiconducting film and the donor concentration is in the order of 1020 . The calculated diffusivity of point defects is in the range of (0.5 to 2.5) × 10˗16 cm2s−Ex- situ ellipsometry measurements were performed to analyze the optical constants of the oxide layer and to determine the oxide thickness. The thickness is in the range of 3.5 to 5.8
