Received March 18, 2005 Abstract — Electrochemical equipment, which enables one to study the processes of underground corrosion under conditions of differential aeration of soils, with no limitation of the experiment duration at a fixed position of the interface boundary and controlled moisture content, is developed. The character and rate of the corrosion process can be predicted by comparing the metal potentials with the polarization curves recorded in soil electrolytes at pH values typical of the near-electrode soil layer. The usage of solely gravimetric technique in studying the above corrosion processes may provide wrong results. PACS numbers: 81.65.Kn, 82.45.Bb, 07.05.Fb DOI: 10.1134/S0033173206060130
