Corrosion modeling is an interdisciplinary undertaking that requires input from electrolyte thermodynamics, surface electrochemistry, fluid flow modeling, and metallurgy. Methods for modeling aqueous corrosion as a function of environmental conditions are reviewed in this chapter. In particular, this review deals with corrosion chemistry by focusing on modeling both the bulk environment and the reactions at the corroding interface. In the first part of the chapter, thermodynamic models of electrolyte solutions are reviewed. These models are used to predict what aqueous and solid species may cause or influence corrosion in a particular system. Further, they show what thermophysical properties and phase behavior can be expected and how they relate to corrosion behavior. In the second part of the chapter, electrochemical kinetics and mass transport models are reviewed. These models are designed to predict what reactions are responsible for corrosion at the metal/liquid interface and how they are influenced by the bulk solution chemistry and by flow conditions. In addition, models are available to predict how passivity and formation of solid corrosion products can be related to environmental conditions. Further, models that predict the threshold conditions for the initiation and long-term occurrence of localized corrosion are discussed. However, models for the spatial and temporal evolution of localized and general corrosion in complex systems and engineering structures are outside the scope of this chapter. Finally, a number of practical applications of corrosion modeling in various industries are outlined.
