Over the last years, Kelvin probe techniques have found a more and more widespread application in corrosion science. While the pioneering applications by Stratmann et al were focused on investigating corrosion underneath ultra-thin electrolyte layers to cathodic delamination of organic coatings [1, 2], over the last 15 years the Kelvin probe method was shown to be applicable for new applications such as mapping hydrogen activities, measuring hydrogen permeation [3] and even measuring oxygen reduction at buried interfaces [4] or on surfaces just covered by a monolayer of water [5].
In this contribution examples about the latest developments of its application in corrosion science will be presented, from coating delamination to hydrogen in materials.
