Applications of Kelvin probe technique in the studies of atmospheric corrosion

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.
