Ⅳ. Electrochemical Measurements in Various Environments―Evaluation Method of Cathodic Protection Condition for Carbon Steel in Seawater―

Abstract

An example of evaluating such important parameters in cathodic protection （CP） as protection potential, protection current density and time variation in cathodic polarization characteristic, was elucidated for carbon steels in seawater as a typical case of diffusion-control of dissolved oxygen. Following the analyses of cathodic polarization characteristic with time, behavior of the galvanic CP using Al-alloy anode was simulated by using the proper ties of potentiostatic CP.
