It is primarily associated with mild steels having a high carbon content and a ferritic-pearlitic microstructure. During corrosion of such steel, the ferrite phase dissolves and a porous iron carbide network is exposed (see Fig. 7.6).Given that iron carbide is an electronic conductor, this porous network serves as ...
