The differential aeration cell and the corrosion paradox

Popis výsledku v původním jazyce

"Steel with a low volume of both anolyte and catholyte was used for monitoring of steel electrode corrosion rates under conditions in the environment of a differential aeration cell under the conditions of both stagnating and exchanging electrolyte. A 3%NaCl solution was used as the electrolyte. A low content of oxygen near the anode was ensured by purging the solution with nitrogen while a high content of oxygen near the cathode was obtained by saturating the solution with oxygen. All experiments wereperformed for 72 h. Corrosion rates of steel electrodes were identified by using the weight loss method in comparison with the resistometric method. The corrosion rate of an aerated electrode drops in stagnating electrolyte to a hundredth of millimetreper year (0.01mm/a) as a result of the catholyte alkalization and subsequent surface passivation, and that it is lower than the corrosion rate of a non-aerated electrode (0.12 mm/a). In a stagnating solution, the catholyte is alkalized (p
