Abstract
A two-electrode sensor with co-surface electrode position was developed for measurement of the instantaneous rate of corrosion of structural steels and welded joints in thin electrolyte films. Performance of the sensor was demonstrated for measurement of the rate of atmospheric corrosion at different temperatures, 100 % air humidity with and without moisture condensation. It was established that under conditions simulating the atmospheric ones the developed sensor can be used to measure the corrosion rate in the 1^.10-6^-10 mm/year range.
