Abstract
The application of electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization measurement were employed for the evolution of corrosion of aluminum alloy (6262) in artificial sea water under the turbulent flow conditions. The flow condition experiments were simulated using rotating cylinder electrode (RCE). The obtained results showed that enhancing the incremental fluid flow velocity, a significant change were occurred in corrosion reaction mechanism and improvement of the corrosion kinetic of the system were also been observed. By increasing the fluid flow velocity, there is an increase in the limiting current. This result conclude the presence of a mixed control on the corrosion process associated with the formation as well as stabilization of obtained corrosion product layers on the investigated electrode surface.
