Data from: A study of bacteria adhesion and microbial corrosion on different stainless steels in environment containing Desulfovibrio vulgaris manuscript

Stainless steel is an important material used in many applications due to
its mechanical strength and corrosion resistant properties. The high
corrosion resistance of stainless steel is provided by the passive film.
Different stainless steels have different alloy elements and surface
properties which could have a significant influence on bacterial
attachment to the surface and thus might result in different microbial
corrosion behaviours. In this study, the effect of adhesion of sulphate
reducing bacteria (SRB) and corrosion behaviour in artificial seawater on
different stainless steels was investigated. Stainless steel materials
used were SS 410, SS 420, SS 316 and DSS 2205 and pure chromium. The
contact angle was measured to study the effect of surface properties of
materials. Adhesion was measured by counting cells attached to the surface
of materials. The corrosion behaviour of the materials was measured by
electrochemical testing including measuring open circuit potential,
electrochemical impedance spectroscopy and potentiodynamic behaviour. The
long-term corrosion behaviour of each material was studied after six
months exposure by measuring weight loss and surface analysis with
SEM-EDX. The results show the high dependency on hydrophobicity of
materials surfaces to bacterial attachment. However, bacterial attachment
did not have a significant effect on the corrosion rate of the materials.
Pure chromium had the best corrosion resistance to MIC with reduced
bacterial attachment compared to the stainless steel samples. The nature
of bacterial attachment and corrosion behaviour of the materials are
discussed.
