Abstract:

Mineralogical data, thermodynamic stability Pourbaix diagrams, and the simplexity 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.
