Open circuit potential study of stainless steel in environment containing marine sulphate-reducing bacteria
The corrosion potential of AISI 304 stainless steel coupons influenced by sulphate-reducing bacteria (SRB) has been studied. Pure colony of SRB was isolated from the Malaysia Marine and Heavy Engineering, Pasir Gudang, Johor. Open circuit potential measurements were carried out in variable types o...

| description | The corrosion potential of AISI 304 stainless steel coupons influenced by sulphate-reducing bacteria (SRB) has been
studied. Pure colony of SRB was isolated from the Malaysia Marine and Heavy Engineering, Pasir Gudang, Johor. Open
circuit potential measurements were carried out in variable types of culturing solutions with SRB1, SRB2, combination of
SRB1 & SRB2 and without SRBs inoculated. The results showed that the corrosion potential, Eoc increased in the presence
of SRBs (in pure and mixed culture) compared to that of control. EDS analysis showed the strong peak of sulphur in
coupon containing SRB cultures compared to the control. Environment Scanning Electron Microscope (ESEM) data showed
that the high density cell of SRBs were associated with corroding sections of surface steel comparing with non-corroding sections for coupons immersed in VMNI medium containing SRBs. |
