A Strategy for Designing Corrosion-Resistant Materials
Billions of dollars are spent each year in the U.S. to repair corrosion damage. To help reduce the high cost of corrosion, engineers at the Naval Research Laboratory (NRL) in Washington, D.C. are using multiphysics simulation to gain a better understanding of the fundamental mechanism. A successful research outcome at NRL will establish the correlation between metal microstructure, corrosion, and mechanical strength. Material designers could then develop stronger, corrosion-resistant materials using this new information.
Intro to Corrosion Modeling for the Oil and Gas Industry
If you work in the oil and gas industry dealing with offshore drilling, corrosion is your worst enemy. A corroded oil platform is a dangerous platform and it can cost you a lot — in both lives and money. To avoid such a dark fate, you need to safeguard the steel structure from corrosion via a protection system, such as the cathodic protection process shown here.
Which Current Distribution Interface Do I Use?
When designing electrochemical cells, we consider the three classes of current distribution in the electrolyte and electrodes: primary, secondary, and tertiary. We recently introduced the essential theory of current distribution. Here, we illustrate the different current distributions with a wire electrode example to help you choose between the current distribution interfaces in COMSOL Multiphysics for your electrochemical cell simulation.
Theory of Current Distribution
In electrochemical cell design, you need to consider three current distribution classes in the electrolyte and electrodes. These are called primary, secondary, and tertiary, and refer to different approximations that apply depending on the relative significance of solution resistance, finite electrode kinetics, and mass transport. Here, we provide a general introduction to the concept of current distribution and discuss the topic from a theoretical stand-point.
Another Danger with Corrosion
One dangerous aspect of corrosion is that it can compromise the stability of structures, which is particularly relevant in the naval industry, where material failure leads to leaks. However, another danger of corrosion has recently become apparent.
A Lot Happening with the New Corrosion Module
This Friday, a training course in modeling corrosion is being run at the COMSOL Burlington office. Participants will be introduced to the new Corrosion Module and will be led through a number of different exercises.
