Background: Results of a study on the initial stage of corrosion damage of carbon steel in
0.5mol/l NaCl by high-precision Coulometric Registration of Corrosion Products (CRCP) of the metal
surface and in the corrosive medium are reported.
Methods: During the measurements, the method of coulometric determination of corrosion products developed
by the authors was used.
Result: An accurate quantitative determination of “initiation phase of corrosion” allowed to find a correlation
between the early stage of the process and its subsequent development of corrosion.
Keywords: Corrosion, initial stage, corrosion products, coulometry, microgram range, measurements.
