Abstract

Corrosion of X80 pipeline steel in an acidic red soil slurry was studied by means of electrochemical impedance spectroscopy (EIS) and polarization technique. The results show that in a water-saturated red soil, the EIS of X80 steel contains a capacitive arc at high frequency and a capacitive arc from the interface process in frequency region of 10^-²~10⁴ Hz as well as an inductive loop appears at low frequency exhibiting processes related with adsorption or pitting nucleation; the electrode process was controlled by diffusion process after 30 d exposure; iron oxides residing in the soil tend to enhance the corrosion process of the steel, correspondingly a corrosion mechanism has been proposed.

Key words: soil corrosion pipeline steel acidic soil red soil
