Galvanic Corrosion of a Magnesium Alloy in Contact with Steel
Application ID: 10914
Magnesium alloys are attractive alternatives as lightweight materials in various fields of engineering. Magnesium is however relatively non-noble and may suffer considerable galvanic corrosion when being used in conjunction with other metals, for instance when mounting an Mg alloy component using steel fasteners.
This model example simulates a galvanic corrosion couple consisting of a magnesium alloy (AZ91D) and mild steel, with salt water (5% NaCl) as electrolyte. The example is based on a paper by J.X. Jia and others.
This model is included as an example in the following products:Corrosion Module
however additional products may be needed to reproduce it. This example may be created and run using components from the following product combinations:
- COMSOL Multiphysics® and
- either the Batteries & Fuel Cells Module, Corrosion Module, Electrochemistry Module, or Electrodeposition Module
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 Specification Chart 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.
