Résumé : 

The effect of the chemical composition on corrosion and the electrochemical behavior of the steel slightly allied prepared according to the standards was studied in the solution of NaCl 3.5% to pH 7.25. The experimental techniques used include the stationary and no stationary electrochemical techniques, to supplement the study we carried out a catch of photograph per optical microscope. The objective of our work is to study some metallurgical characteristics of corrosion by NDE. The characterization of the microstructure modifications by eddy currents allows detecting mechanical and metallurgical parameters of materials will be compared to the results of electron microscopy and micro-hardness.
