Getting Started with Electrochemical Corrosion Measurement
Most metallic corrosion occurs via electrochemical reactions at the interface
between the metal and an electrolyte solution. For example, a thin film of moisture
on a metal surface forms the electrolyte for atmospheric corrosion. A second
example is when wet concrete is the electrolyte for reinforcing rod corrosion in
bridges. Although most corrosion takes place in water, corrosion in non-aqueous
systems is not unknown.
