Evaluation of the fraction of surface defects for the corrosion-resistant coatings of the mains

We propose a mathematical model for the evaluation of the fraction of surface defects in corrosion-resistant coatings, current densities in these defects, and the corresponding values of the polarization potential and polarization resistance. To find these values in the model, we the use the results...

Summary:We propose a mathematical model for the evaluation of the fraction of surface defects in corrosion-resistant coatings, current densities in these defects, and the corresponding values of the polarization potential and polarization resistance. To find these values in the model, we the use the results of electrometric measurements along the route of a main and the parameters of polarization curves.
