Production of Sulfide Minerals by Sulfate Reducing Bacteria duringMicrobiologically Influenced Corrosion of Copper

摘要

Mineralogical data, thermodynamic stability (Pourbaix) diagrams, and thesimplexity principle for precipitation reactions were used to evaluate corrosion product mineralogy on copper alloys exposed to sulfate-reducing bacteria. The formation of copper sulfides as corrosion products in natural surface environments is suggestive of microbiologically influenced corrosion. Sulfide corrosion products other than chalcocite (Cu2S) indicate that reactions within a biofilm induced corrosion. Biofouling, corrosion, biodeterioration, electrochemistry.
