Sažetak
Cathodic protection (CP) is an electrochemical method of protecting metallic constructions against corrosion. The problem of CP design amounts to the well known problem of mathematical physics &#8211 ; calculation of potential and current distributions by solving the Laplace equation with the appropriate boundary conditions. The problem may require incorporation of various electrochemical and hydrodynamic effects, multiple boundaries, nonheterogenous electrolyte, time-dependent effects etc. Traditional CP design methods are mostly based on simple empirical formulas that require the use of large safety factors and rely, to a great extent, on the engineer&#8217 ; s experience. Modern CP design methods utilize explicit mathematical modelling. In the present work, boundary element solutions for the potential and current distributions in CP systems of increasing geometrical complexity have been calculated and visualized in Mathematica. The Laplace equation is solved in 2-D with nonlinear boundary conditions defined by the polarization curves measured in situ. Comparison is made with the potential distribution measured in the simple, laboratory CP system. The problem is extended to external, multiple-boundary system with an infinite electrolyte boundary. The most influential factors of CP design are analysed.
