Corrosion and Transport Processes in Cracks
Abstract
A numerical method for solving the electrochemical transport equations subject to an arbitrary set of charge-transfer boundary conditions is presented. The method is based on a two-dimensional time-dependent formulation of the equations derived from dilute solution theory. It is applied to a study of corrosion and transport processes in crack-like regions. The results show that the average species fluxes normal to the metal-electrolyte interface, the crack length, and the crack aspect ratio are the most important factors affecting the electrolyte composition. Other factors, such as the crack shape, the form of the boundary conditions, and the transport mode, also affect the composition; but, these factors are of secondary importance.
