An electrochemical sensor which incorporates a counter electrode (CE) and a reference electrode (RE) into an O-ring has been developed for in situ monitoring of crevice corrosion initiation and propagation. It is applicable to crevice corrosion situations where the crevice is created by a gasket or an O-ring and the attack occurs in that crevice. It is shown that polarization resistance (R{sub p}) values calculated from in situ electrochemical impedance measurements correlate with the onset of crevice attack and with its propagation for crevice corrosion of alloy 625 (UNS N06625) in 3.5% NaCl and in 10% FeCl{sub 3} solutions.
