Abstract

A mathematical model of the galvanic iron corrosion is, here, presented. The iron(III)-hydroxide formation is considered together with the redox reaction. The PDE system, assembled on the basis of the fundamental holding electro-chemistry laws, is numerically solved by a locally refined FD method. For verification purpose we have assembled an experimental galvanic cell; in the present work, we report two tests cases, with acidic and neutral electrolitical solution, where the computed electric potential compares well with the measured experimental one

The mathematical model presented in Botte, Mansutti and Pascarelli, App. Num. Math. (2005) has been here improved and numerically tested on a in-house laboratory experiment. This paper contains the same results in the publication n.8 in the list submitted to ANVUR, with the purpose to put them to the attention also of technically specialized readers. Besides the institutional funding from C.N.R. in benefit of one author, we acknowledge the financial support of Soprintendenza ai Beni Culturali Regione Autonoma Valle d'Aosta (project "Analisi di processi di corrosione di materiali ferrosi", 2003-2005, PI Daniela Mansutti) that allowed this research to be.
