Abstract

This paper investigates the deposition of calcareous material on carbon steel through cathodic protection. A Response Surface Methodology (RSM) was applied to model the electrodeposition of calcareous material in ASTM seawater by varying temperature and current density parameters. The calcareous deposit was more compact at a current density ≤ 150 µA/cm2. At least 55 µA/cm2 current density was required to provide cathodic protection and initiate electrodeposition, thus inhibiting corrosion. Furthermore, the produced RSM models can predict the amount and composition of the material at 55 – 310 µA/cm2 current density and 4 – 25 °C temperature.
