Corrosion mechanisms of UNS N04400 in sea water

Pitting and dealloying were observed when 70Ni/30Cu (UNS N04400) welded plates were exposed to artificial seawater containing sulfate-reducing bacteria. Attempts were made to differentiate biotic and abiotic corrosion mechanisms. Experiments were conducted in alternating aerobic/anaerobic conditions...

Zusammenfassung:Pitting and dealloying were observed when 70Ni/30Cu (UNS N04400) welded plates were exposed to artificial seawater containing sulfate-reducing bacteria. Attempts were made to differentiate biotic and abiotic corrosion mechanisms. Experiments were conducted in alternating aerobic/anaerobic conditions in the presence of inorganic sulfide and sulfatereducing bacteria over the course of five months.
