| Résumé : |
Corrosion of different materials (Cu, Al, Al–Cu and C-steel) in soil solution was evaluated at ambient temperature using various techniques. The weight loss of the studied materials varied exponentially with time. Kinetic data revealed that the corrosion of Cu and Al–Cu are diffusion controlled while Al and C-steel show gradual change from diffusion control to charge transfer control. Nonferrous materials have better durability factors than C-steel. Good consistency between the data obtained from EIS and PDP measurements was observed. SEM showed a biogenic corrosion layer with density that depends on the metal type. Correlation between corrosion rates and the estimated soil solution corrosivity was obtained.
