Abstract

Numerical modeling has become a trend in galvanic corrosion research. We summarize the forms of corrosion and focus on the galvanic corrosion, especially about the corrosion of magnesium and its alloys. We discuss the governing equations and the boundary conditions of galvanic corrosion. Based on the present status of galvanic corrosion research, we model the corrosion processes of magnesium alloy when the protective films (one situation is with high resistivity film and another is with zinc) are broken. We introduce the finite element method (FEM) and finite differential method (FDM) as tools for modeling and use FEM to solve an equation with different boundary conditions as a sample calculation and get some meaningful results.
