Measuring corrosion rate of mild steel by three different techniques; Polarization Resistance, EIS, and our newest technique, Electrochemical Frequency Modulation, or EFM for short.
Corrosion and Coatings
Electrochemical testing is a mainstay of many corrosion and coatings laboratories throughout the world.
Localized corrosion, including crevice corrosion, is a leading cause of corrosion-induced failures. THE Method (Tsujikawa-Hisamatsu-Electrochemical Method) has been proposed to measure crevice corrosion repassivation potentials.
Most metallic corrosion occurs via electrochemical reactions at the interface between the metal and an electrolyte solution.
