Early stages of copper corrosion behaviour in a Tunisian soil / N. Souissi in Materials and corrosion, Vol. 61 N° 8 (Août 2010) 

Public ISBD [article]  in Materials and corrosion > Vol. 61 N° 8 (Août 2010) . - pp. 695–701 Titre : Early stages of copper corrosion behaviour in a Tunisian soil Type de document : texte imprimé Auteurs : N. Souissi, Auteur ; E. Triki, Auteur Année de publication : 2010 Article en page(s) : pp. 695–701 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Copper;  corrosion;  electrochemical  characterization;  soil;  surface  analysis Résumé : The early stages of copper corrosion in a Tunisian soil were studied using mass loss, surface analysis (optical microscopy, visible spectroscopy, IRTF and atomic force microscopy) and electrochemical characterizations (polarization curves and cyclic voltammetry). The corrosion rate dependence with immersion time was Δm = atb. Two behaviours for the material surface were evidenced when varying the soil concentration and temperature. Then, the apparent kinetic constant, the soil reaction order and the apparent activation energy were calculated. Analytical and electrochemical characterizations showed that a rough patina layer was build up as a result of the interaction between soil and copper.
