Electrochemical Response of Aluminum and Al Alloy Anodes in Seawater for Cathodic Protection: A Finite Element Method Study
Abstract
This study investigated the electrochemical performance of pure Al and Al alloy anodes in Sw environments for CP real-world applications, such as marine environments, under various operational conditions.Experimental results showed a significant activation of Al alloy anodes compared to pure Al, as indicated by a more anodic shift in OCP and a marked increase in jcorr.The impact of varying DAC and changes in Sw conductivity on CP performance was also herein explored.These factors notably influenced both Ecorr and j from CP, resulting in deviations from expected design values.
