AbstractThe effect of elastic stress on corrosion of X80 steel in an acidic soil solution containing sulfate-reducing bacteria (SRB) trapped under a simulated disbonded coating was investigated. The SRB numbers at the coating holiday after 14 days were approximately 106 cells/mL, and they were higher than those in the simulated disbonded coating region. The stressed coupons underwent more severe SRB corrosion and pitting at the same locations under the simulated disbonded coating due to the mechanochemical effect. These results indicated that the pitting process was affected by the applied elastic stress in the X80 steel.
