POLARIZATION AND RESISTIVITY STUDY OF TITANIUM IN NEUTRAL CHLORIDE SOLUTION

The total anodic voltammetric characteristics of titanium in chloride solution at pH = 5.9 were determined for the first time by separation of the anodic component from the cathodic polarization curves. The app earance of anodic currents during cathodic polarization was confirmed by resistivity measurements. The mechanism of electrochemical corrosio n and passivation of titanium was proposed. The results obtained were used io explain the poor resistance of titanium alloys to corrosion cr acking in a certain interval of cathodic polarization potentials in ne utral chloride solutions.
