✦ Synopsis

Abstract

Based on the corrosion behaviour of stainless steels in fresh water and on the electrochemical properties of higher manganese oxides, the mechanism “Microbially influenced corrosion by manganese oxidizing microorganisms” (MIC by MOMOs) is presented as the consequence of biomineralized manganese oxides in contact with the metal. Localized corrosion may develop at elevated but normally undercritical chloride concentration in the water. The mechanism was found useful in the analysis of certain cases of unexpected failure of stainless steel in fresh water.

Manganese oxidizing microorganisms are known as ubiquitous species in soil and fresh water. Their ability to extract dissolved manganese even at minute concentrations from the water and to biomineralize it as manganese(III/IV)oxides makes them potentially relevant for corrosion processes in technica
