Localized Corrosion Using the Phase Field Method
Application ID: 79851
This example models galvanic corrosion between two different phases in a magnesium alloy for a representative cross-sectional microstructure configuration.
The Phase Field interface is used here to model dissolution of a constituent phase leading to topological changes. The electrode kinetics at the corroding boundary is defined as a domain term making use of the phase field delta function.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® et
- soit le Module Battery Design, Module Corrosion, Module Electrochemistry, Module Electrodeposition, ou Module Fuel Cell & Electrolyzer et
- soit le Module CFD, Module Corrosion, Module Electrodeposition, Module Microfluidics, ou Module Polymer Flow
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Grille des Spécifications and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
