钢在海洋沉积物中的腐蚀电化学测量技术

中国科学院海洋研究所 青岛266071
摘要:
1998年3月在中国科学院海洋研究所设计了一个新型电解地，以满足试 样在海洋沉积物中极化曲线测量的需要。该电解池装有二个参比电极，它们距工 作电极之间的距离可以精确调节。介质电阻对极化曲线的影响可以通过计算不同 电位下的介质电阻予以消除。模拟电路和实际体系的测量结果表明，该实验技术 可以用于海洋沉积物腐蚀电化学的研究中。

POLARIZATION CURVE MEASUREMENT OF STEEL IN SEA-BOTTOM SEDIMENT

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.
