The Effects of Ag-Cu Ions on the Microbial Corrosion of 316L Stainless Steel in the Presence of Desulfovibrio sp

摘要

The effects of Ag-Cu ions on the microbiological corrosion of 316L stainless steelrn(SS) in the presence of Desulfovibrio sp. were investigated. The corrosion behaviorrnof 316L SS was analyzed by potentiodynamic polarization and electrochemicalrnimpedance spectroscopy (EIS). The biofilm, corrosion products and Ag-Cu ions onrnthe surfaces were investigated by using scanning electron microscopy (SEM) andrnenergy dispersive X-ray spectrometry (EDS). It was found out that Desulfovibrio sp. isrncorrosive for 316L SS. The Ag-Cu ions reduced the corrosion rate of 316L SS causedrnby Desulfovibrio sp..
