This paper presents the behavior of Alloy C-276 and T60 titanium, submitted to anodic polarization under steady-state and quasi-stationary conditions in oxidative chlorinated aqueous media. The measurements were carried out at temperatures and pressures from usual conditions (20 °C, 0.1 MPa) to supercritical conditions (400 °C, 28 MPa). The influence of various parameters such as pH, chloride ions activity, nature of materials, sub or supercritical state of the medium, was investigated. The effect of the temperature gave rise to the determination of activation energies of the dissolution–passivation processes. The hierarchy of the electrochemical behavior of the materials confirmed the results already obtained in a prevoius work using the determination of corrosion rates.Read less <
