Electrochemical and Surface Insights Into X12CrMoWVNbN10‐1‐1 Steel Corrosion in Chloride Solutions at Variable pH

Materials and Corrosion, EarlyView.
The corrosion performance of X12CrMoWVNbN10‐1‐1 steel in chloride environments dramatically depends on pH. Acidic conditions trigger intense surface degradation, whereas neutral and alkaline media foster the formation of a compact and stable passive film, drastically reducing both general and localized corrosion.
