摘要

In this study, the effect of seasonal variability on the marine environment in the corrosion of Cu and Cu-Alloys was analyzed in situ with respect to exposure time. The possible changes in the mechanism of degradation, considering the physicochemical parameters of seawater were studied. An electrochemical study was carried out with three metallic materials industrially used (copper, bronze and brass) for 10 months of continuous exposure in seawater surrounding the San Juan de Ulua Fortress in Veracruz port, Mexico. Electrochemical impedance spectroscopy (EIS) was the electrochemical technique used. Additionally, a characterization of the metal surface with scanning electron microscopy (SEM) and X-ray diffraction (XRD) was carried out. All materials showed good corrosion resistances; however, copper showed higher resistance which took their best values in the last months of exposure presenting a layer of products of Cu2O. Additionally, some silicates and sulfates were detected. Pitting and localized corrosion type was observed.
