Kelvin探头参比电极技术在大气腐蚀研究中的应用

APPLICATIONS OF KELVIN PROBE TECHNIQUE IN THE STUDIES OF ATMOSPHERIC CORROSION

Kelvin探头参比电极技术是近年来大气腐蚀领域中最为活跃的研究方向之一 .它能够不接触、无破坏的检测薄液膜甚至涂层下金属表面的腐蚀电位分布 .文中介绍了该技术的发展历史、技术要点 。

Since the Kelvin probe technique has been introduced into the studies of atmospheric corrosion,it has been paid increasing attention by corrosion scientists in the past decade due to its ability to measure the metal surface covered by very thin electrolyte layer,the corrosion potential and its distribution yet without touching the metal and electrolyte.In this paper,the history and properties of this technique were reviewed,also the applications on delamination of organic coatings and corrosion of metals under thin electrolyte were discussed.
