Galvanic Corrosion Analysis
How is galvanic corrosion risk calculated?
Galvanic corrosion risk is calculated using mixed potential method.
Why does the MIL-STD-889D chart show different results?
The MIL-STD-889D uses a different method to the mixed potential method to calculate galvanic corrosion risk.
The MIL-STD-889D uses the summed anodic and cathodic reactions for each curve rather than crossing the polarization curves to calculate the galvanic corrosion risk, so there are slight differences for the results.

Include Material Areas
Adding material area information provides a better prediction of galvanic corrosion by taking into account the cathode to anode area ratios.
