Abstract
Real-time corrosion monitoring for carbon steel materials in soil was conducted utilizing coupled multielectrode sensors. It was demonstrated that the coupled multielectrode sensor is an effective real-time tool for monitoring the corrosion rate in soil. The steady state corrosion rate measured in water-saturated soil was found to be approximately 2 to15 μm/year. However, the corrosion rate in a space filled with water was several orders of magnitude higher than those found in the densely packed soil saturated with water. The coupled multielectrode sensor also provided real-time indications for the effectiveness of cathodic protection in soil.
