The Electrochemical Family is Extended
Phil Kinnane | April 30, 2012
We’re increasing the electrochemical family of products with the next version of COMSOL. Joining the Batteries & Fuel Cells and Electrodeposition Modules will be the Corrosion Module. This will allow for the modeling of all types of electrochemical corrosion (galvanic, pitting, etc.) as well as corrosion protection. This has been an exciting development and is the response to a number of COMSOL users who have requested it.
The above image shows the type of modeling that can be done. A magnesium alloy and mild steel are connected in a salt water environment. As all high-school scientists know, the connection of different metals like this usually leads to corrosion. What is seen is the corrosion of the magnesium alloy over time. The model takes into account the change in the geometry as a result of this corrosion, and the corroding current density (streamlines) changes as a result of this.
