Rybalka, K.V., Beketaeva, L.A. & Davydov, A.D. Study of Anodic Dissolution of Stainless Steel in HCl by the Method of Measuring Ohmic Resistance. Russ J Electrochem 56, 239–242 (2020). https://doi.org/10.1134/S1023193520030106

The aim of the work is to show the potentialities of the method of measuring ohmic resistance for investigating the anodic dissolution of metals. It is shown that simultaneous measurement of metal dissolution rate by using this method (by a change in the specimen weight, which is calculated by a change of its resistance) and by the charge consumed for the metal polarization enables us to determine the electrochemical equivalent of stainless steel. The dependence of cathodic component of the current on the anodic potential is obtained and the potential range adjacent to the open-circuit potential, where both anodic and cathodic reactions should be taken into account, is determined.
