Abstract:

A numerical method has been developed to predict corrosion states of wetted dissimilar metals in the electrolyte of a galvanic system. The method employs the finite element technique with computer implementation to solve for the potential distribution throughout the system of arbitrary geometry. The method fully accounts for the metals nonlinear electrode kinetics and imposes charge conservation to agree with mixed potential theory. Computational corrosion analysis is now a mature technology and has been used successfully in performing corrosion-resistant design and in addressing corrosion problems. This paper describes the theory behind this development, the uses of this method, an analysis problem already solved, and current research extending this method to microcorrosion problems. Keywords Computer simulation Electronics Corrosion Computational corrosion analysis Cathodic protection design Finite element analysis.
