The effects of coating defect, cathodic protection, and sulphate-reducing bacteria on corrosion of EH40 steel
Source abstract
Abstract
The effects of coating defect, cathodic protection (CP), and sulphate-reducing bacteria (SRB) on EH40 steel corrosion were investigated in seawater. Results showed that the presence of − 0.85 V CSE and SRB result in the current density fluctuate around 0 μA·cm −2 for EH40 steel with different coating defects. EH40 steel corrosion with coating defect of 0.2 mm is inhibited, but promoted with 1.0 mm and 2.0 mm under effects of − 0.95 V CSE and SRB. The CP of − 0.95 V CSE and current density of − 0.6 μA·cm −2 inhibit adhesion of SRB on EH40 steel with coating defect of 0.2 mm.
