Abstract
Changes in the surface concentrations of the main alloying elements of an as-received 304 stainless steel, exposed to a mixed culture of bio film-forming bacteria under flowing conditions, were observed using Au ger electron spectroscopy. In the oxide film close to the bulk stainle ss steel, there was an enrichment in the relative concentration of Cr with a corresponding decrease in the relative Fe concentration as comp ared to a control coupon exposed only to sterile media. There were no changes observed in the relative Ni concentration. (C) 1996 American V acuum Society.
