Abstract

The conditions for electrocoating formation on carbon steel in flowing tap water were investigated. The cathodic polarization tests were carried out galvanostatically. Electrocoating started within one day by giving larger cathodic current than diffusion current of oxygen. The condition for electrocoating formation was also obtained from electrode potential whose value was less than -0.73V vs. SHE. The presence of electrocoating reduced protection current density by a factor of about ten.
