Iron sulfide corrosion product layers commonly form on mild steel surfaces corroding in aqueous H 2 S environments. These porous layers present a barrier which may reduce the corrosion rate, however, their semi-conductive nature leads to an acceleration of corrosion via galvanic coupling, by increasing the cathodic surface area.
