Respirometric In Situ Methods for Real-Time Monitoring of Corrosion Rates: Part II. Immersion

With the aim to open a new window into corrosion processes this paper presents respirometric methods for real-time in situ monitoring of rates under immersion conditions. these techniques, sensitive, non-destructive rate measurements are possible on basically all metals and alloys. Different presented that enable monitor HER, ORR or both reactions simultaneously based amount evolved H 2 consumed O by volumetric, manometric sensor-based approaches. Various research examples presented, demonstrating benefits limitations different For Mg alloys, besides plays role cathodic good correlation total charge with mass loss was obtained. dissolution electrolyte identified as an important factor. The results obtained Zn intermittent-flow flow-through experiments suggest mechanism leads generation stable As result, effective number exchanged electrons one molecule found be between two four. here introduced techniques allow insights mechanisms, addition enabling corrosion.
