The effect of hydrodynamics on the corrosion of Al – 14 wt% Zn – 8 wt% Mg alloy in artificial seawater media at room temperature was studied in a rotating cylinder electrode, RCE, system under turbulent flow conditions. Five different rotation rates were studied: 0 (or stagnant conditions), 1000, 3000, 5000 and 7000 rpm. The corrosion rates were measured by electrochemical impedance spectroscopy (EIS). For the system studied, corrosion potential, Ecorr becomes more positive with increasing of the rotation rate of RCE (Reynolds number, Re). The effect of increasing the Re number is to enhance the availability of oxygen at the electrode surface, which in turn will polarize the corrosion reaction in the more noble direction.

Based on some articles that have been published in Materials Performance (MP) and the NACE Courses 9 and Standards for Cathodic Protection (CP) practitioners, this author has concluded that present day CP practitioners, do not have an adequate understanding of some basic scientific principles.
