Method for Measuring Localized Corrosion Rate with a Multi-Electrode Array Sensor

Abstract: 

A method of measuring localized corrosion, using a multi-electrode array sensor. The method eliminates the effect of internal current in corroded electrodes, and thus provides a more accurate corrosion measurement. In one embodiment, the potential of a common node of the sensor is adjusted so that the sensor's most cathodic current is close to zero.
