Research Achievement：

The effect of sulfate reducing bacteria (SRB) on the corrosion of the carbon steel Q235 has been investigated in the crevice under the simulated disbonded coating in the soil-extract solutions. EIS show that the corrosion rate is inhibited in the SES with SRB during the stationary phase of SRB, but enhanced during the death phase.

We have studied effect of SRB and stress on corrosion of pipeline steel and found that SRB and elastic stress have synergistic effect on accelerating corrosion of pipeline steels.

Corrosion of pipeline steel in acidic red clay soil was investigated, and an auto-catalyzed kinetic mechanism is proposed to clarify high corrosivity of red clay soils.

We also focus on corrosion and corrosion control technique related to stray current corrosion of pipeline, e.g. evaluating the cathodic protection and coating systems.
