Electrochemical corrosion behaviour of a Ti-IF steel and a SAE 1020 steel in a 0.5 M NaCl solution / W. R. Osório in Materials and corrosion, Vol. 61 N° 5 (Mai 2010) 

Public ISBD [article]  in Materials and corrosion > Vol. 61 N° 5 (Mai 2010) . - pp. 407–411 Titre : Electrochemical corrosion behaviour of a Ti-IF steel and a SAE 1020 steel in a 0.5 M NaCl solution Type de document : texte imprimé Auteurs : W. R. Osório, Auteur ; L. C. Peixoto, Auteur ; A. Garcia, Auteur Année de publication : 2010 Article en page(s) : pp. 407–411 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : corrosion;  electrochemical  impedance;  low  carbon  steel;  microstructure Résumé : Investigations concerning the electrochemical corrosion behaviour of low carbon (LC) and ultra-low carbon (ULC) steels are relatively scarce and limited. The present study aims to compare electrochemical impedance parameters and potentiodynamic polarization curves of an LC steel and an ULC Ti-interstitial free (IF) steel evidencing the effects of carbon content and pearlite fraction on the electrochemical corrosion behaviour. Corrosion tests were carried out in a 0.5 M NaCl solution at 25 °C with a pH range between 6.5 and 6.8. It was found that the IF steel sample presents an electrochemical corrosion resistance, which is slightly higher than that of the LC steel sample.
