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:
