Abstract: |
A new electrochemical cell with two reference electrodes was designed to meet the requirement of sea-bottom sediment resistance correction in the measurement of polarization curves. The distance between the reference and working electrodes can be adjusted accurately. The effects of resistance can be eliminated by an analysis of resistance for different potentials, using the measured data of reference electrodes. The results of the simulation circuit and real systems show that this method is valuable in the study of corrosion electrochemistry of steel in sea-bottom sediment. |
