Mathematical Modeling of Cathodic Protection Using the Boundary Element Method with a Nonlinear Polarization Curve
Journal of the Electrochemical Society
The distributions of potential and current density around a cathodically protected pipeline in seawater were determined using the boundary element technique. A nonlinear polarization curve for a low carbon steel in artificial sea water was obtained from dc-potentiodynamic measurements and was fitted for use as the boundary condition on the pipe. The program was used to evaluate cases in which one or two aluminum sacrificial anodes are used to protect a low carbon steel pipe in seawater. The results show that the number of anodes, the sizes of the anodes, and the distance between the anodes and the cathode are of importance for cathodic protection. © 1991, The Electrochemical Society, Inc.
