Abstract A multielectrode localized corrosion sensor was developed and used for comparing localized corrosion of Fe-Ni-Cr-Mo alloys in chloride solutions. Experimental results indicated that the coupled multielectrode sensor provides a rapid real-time response to changes in temperature and salt concentration. It was demonstrated that the sensor has a lower detection limit of 5×10-11 A with respect to corrosion current and 2o10-8 A/cm2 with respect to the corrosion current density for the miniature electrodes used in the sensors.
