When the corrosion inhibitor concentration was increased to 100 ppm, the self-corrosion current density I coor reached a minimum of 2.207 × 10 −5 A/cm 2 , the charge transfer resistance reached a maximum of 932.5 Ω·cm 2 , and the corrosion inhibition efficiency reached a maximum of 95.2%, and the corrosion inhibition efficiency showed a trend of increasing and then decreasing with increasing concentration.
