Effect of iron exposure in SRB media on pitting initiation

Effect of iron exposure in SRB media on pitting initiation

Pitting corrosion of iron (99.9%) in Sulphate-reducing bacteria (SRB) media containing 0.09–0.30 g/l sulphides and 0.1–5.0 g/l [Cl −] was studied. Iron electrode immersed in SRB media undergoes fast activation and numerous active sites formed on the surface. Depending on exposure time, pitting was i...

Zusammenfassung:Pitting corrosion of iron (99.9%) in Sulphate-reducing bacteria (SRB) media containing 0.09–0.30 g/l sulphides and 0.1–5.0 g/l [Cl −] was studied. Iron electrode immersed in SRB media undergoes fast activation and numerous active sites formed on the surface. Depending on exposure time, pitting was initiated at different potentials. After short period (
