Cathodic Kinetics during Corrosion of 5456-H117 Aluminum Alloy by High Velocity Sea Water,

Abstract

The purpose of this investigation was to measure limiting oxygen diffusion current densities as a function of velocity, to study cathodic kinetics on 5456-H117 aluminum alloy as a function of velocity and to conduct constant potential tests at more active potentials than -0.9 V(SCE). Constant potential tests were conducted at selected velocities at potentials more active than -0.9V(SCE) to determine if pitting could be suppressed at the more active potentials. Finally, a model was proposed to explain the observations from this and previous studies.
