摘要
设计了一种研究金属在薄层液膜下电化学行为的三电极腐蚀电池.该电池在降低研究电极和参比电极之间IR的同时消除了参比电极中离子对薄层液膜的污染,并且易于操作.通过稳态极化曲线和交流阻抗技术研究了该电池在薄层液膜下和在大量电解质溶液中的电化学行为,证明了该电池适合研究金属在大气中的电化学腐蚀行为.
A suit of electrochemical cell which was used to investigate corrosion behavior of metals under a thin electrolyte film was designed. The cell eliminated contaminants of ions from reference electrode for thin electrolyte while it diminished the value of IR between working electrode and reference electrode. In addition, it was ease to operate. The electrochemical corrosion behavior of the cell under thin electrolyte film and in bulk electrolyte was comparatively investigated using polarization curve and EIS technique. The results showed that it was proper to use the cell to investigate the electrochemical corrosion behavior of metal in atmosphere.
