Corrosion study of the X52 steel immersed in seawater with a corrosion inhibitor using a rotating cylinder electrode / Garcia-Martinez, R. in Materials and corrosion, Vol. 61 N° 10 (Octobre 2010) 

Public ISBD [article]  in Materials and corrosion > Vol. 61 N° 10 (Octobre 2010) . - pp. 872–876 Titre : Corrosion study of the X52 steel immersed in seawater with a corrosion inhibitor using a rotating cylinder electrode Type de document : texte imprimé Auteurs : Garcia-Martinez, R., Auteur ; R. Orozco-Cruz, Auteur ; R. Torres-Sanchez, Auteur Année de publication : 2011 Article en page(s) : pp. 872–876 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Corrosion  inhibitor;  impedance;  Rp;  turbulent  flow;  X52  steel Résumé : A corrosion study of API X52 steel was carried out in natural seawater with several concentrations of a corrosion inhibitor (10, 100 and 200 ppm) using a rotating cylinder electrode (RCE) to control the hydrodynamic conditions at environment temperature, atmospheric pressure and 24 h of the exposition time. The rotation speed used was 1000 rpm (turbulent flow). The electrochemical techniques used in the corrosion studies were: linear polarisation resistance (LPR), electrochemical impedance spectroscopy (EIS) and polarisation curves (PCs). The superficial analysis was made using a scanning electron microscope (SEM). The results show a good correlation between electrochemical techniques used. In addition, under turbulent flow, the test solution with 10 ppm had the smallest corrosion rate (CR). It is important to mention that the morphology of the corrosion in all experiments was localised corrosion.
