COMSOL_Modeling Corrosion and Corrosion Protection
INTRODUCTION
Almost every man-made structure involves the use of metals; often, nonnoble metals that are susceptive to corrosion. The estimated worldwide costs for corrosionderived damages are about 2.5 trillion dollars. Proper corrosion protection could save 15–55% of the cost of these damages (Ref. 1). We can therefore safely claim that understanding corrosion and corrosion protection is financially well motivated.
Mathematical modeling and simulations are very efficient tools for understanding corrosion and corrosion protection. A validated high-fidelity model, based on the thermodynamics and kinetic properties of a system, can not only be used for understanding but also for making predictions, strengthening intuition, and fostering innovations.
This paper presents the basic theory behind the models that describe corrosion and corrosion protection. It also exemplifies how these models can be used for understanding, innovating, and optimizing devices and processes in order to mitigate corrosion.
