Cathodic protection
Cathodic protection is used to control corrosion in many structures that are in a corrosive environment. However, in many cases this protection may not be complete or accurate, or precise access and monitoring of all parts of the structure may not be possible, which may ultimately lead to Demolition earlier than the design life of the computer Simulation enables the monitoring and verification of the protection system accuracy and hence plays a significant role in corrosion control. On the other hand, the electrochemical problem of cathodic protection is an indefinite external problem and can be mathematically expressed by the simple Laplace equation with nonlinear boundary conditions and simulated boundary element simulation method. It was simulated using the boundary element method and its appropriate software that the results were in good agreement with the results of the field potential measurements in the field. Then, using the simulation it was shown that at higher percentages of coating defects, the initial system Loss of performance and able to provide palate protection L is not on the surface. It was also attempted to provide complete protection for higher coating defects by increasing the number of sacrificed anodes on the surface.
