Role of Conductive Corrosion Products in the Protectiveness of Corrosion Layers

In carbon dioxide (CO2) corrosion of steels, the bicarbonate ion (HCO3) is simultaneously the buffer for carbonic acid (H2CO3), the source of iron carbonate (FeCO3) precipitation, and the product of the cathodic reaction. In addition to spatial separation of the production of Fe2+ and HCO3, galvanic coupling between the steel and cementite (Fe3C) layers is the principal cause of internal acidif...

Metallic plate corrosion and uptake of corrosion products by nafion in polymer electrolyte membrane fuel cells.

Nafion contamination by ferrous-alloy corrosion products, resulting in dramatic drops of the Ohmic potential, is a suspected major failure mode of polymer electrolyte membrane fuel cells that make use of metallic bipolar plates. This study demonstrates the potential of scanning transmission X-ray microscopy combined with X-ray absorption and fluorescence microspectroscopy for exploring corrosio...
