The use of the scanning electrochemical microscopy to predict the corrosion resistance results which would be obtained for a surface S1 having undergone an anticorrosion treatment if the surface S1 was subjected to a salt fog corrosion test, which use comprises an analysis of the surface S1 by scanning electrochemical microscopy.

Use of scanning electrochemical microscopy as a predictive technique in a salt fog corrosion test

The invention relates to the field of localized surface analysis, characterization and modification by electrochemistry. It particularly relates to a portable electrochemical microscopy device, to kits comprising such a portable device, and to uses of the portable device and kits. According to the invention, the portable device comprises: a body having a gripping surface for a user and a bearing surface that can be applied to a surface of a substrate to be analyzed; an electrolytic chamber formed in the body and arranged so as to receive an electrolyte, the electrolytic chamber comprising an opening leading to the bearing surface; and a working probe having a distal end arranged in the electrolytic chamber.
