Experimental Confirmation of a Mathematical Model for the Design of Cathodic Protection Systems

This work deals with the experimental confirmation of a boundary element model developed for the calculation of current and potential distribution in sacrificial anode or impressed current cathodic protection systems. Tests have been carried out with cell in 3. 5% NaCl solution and under variable hydrodynamic conditions. The cathode was made of a carbon steel sheet divided into small elements on which current and potential have been measured. The data obtained from a computer run are in agreement with experimental results.
