Current and Potential Distributions for a Freely Corroding Disk Electrode
Current and Potential Distributions for a Freely Corroding Disk Electrode
This Demonstration shows the process of corrosion in a disk-shaped metal electrode. The potential distribution (blue curves) and the current distribution (red curves) are shown on the left for the vertical distance represented by the red point. A contour plot of the equipotentials is shown on the right. You can vary the radius of the disk-shaped electrode (black bar) to investigate the affect of the size of the electrode on the corrosion.
