Sensors have been developed and manufactured by microelectronic fabrication techniques to directly measure corrosion rates and to determine the effectiveness of corrosion control systems. Microsensors based on measurements of corrosion rate by linear polarization, electrical resistance change, and galvanic currents have been devised. Analytical measurements by potentiometric and amperometric techniques using thick-film planar transducers are illustrated. The use of generic sensor elements individually and in combination to attest the status of corrosion control and to provide data for the evaluation of future performance is highlighted.
