Zinc galvanized steel sheets crystal size influence in environments containing chlorides and sulfates
This paper studied the influence of the zinc crystal size in the electrochemical behavior of steel sheets hot-dip galvanized. The tests were performed in an electrochemical flat cell in solutions with different concentrations of NaCl and NaSO4. The rate, mechanism of corrosion and the resistive and...

Los ensayos se realizaron en una celda electroquímica plana en soluciones con diferentes concentraciones de NaCl y NaSO4. La velocidad y el mecanismo de corrosión, así como las características resistivas y difusivas de las láminas se evaluaron mediante técnicas electroquímicas, como espectroscopia de impedancia electroquímica (EIS), resistencia a la polarización (Rp) y curvas potenciodinámicas. La composición y distribución de los productos de corrosión (FeO y algunos compuestos de cinc) y el daño superficial causado por estos se determinaron por medio de DRX y SEM-EDS. Los resultados mostraron que la degradación de la capa de óxidos formada se ve afectada por la presencia de cloruros que penetran, llegan a la superficie del metal base y generan corrosión localizada.application/pdftext/htmlspaspaUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ingenieria/article/view/3552/3174https://revistas.uptc.edu.co/index.php/ingenieria/article/view/3552/4329Revista Facultad de Ingeniería; Vol. 24 No. 39 (2015); 99-108Revista Facultad de Ingeniería; Vol. 24 Núm. 39 (2015); 99-1082357-53280121-1129galvanized steelcorrosionchloridessulphatesresistance polarizationelectrochemical impedance spectroscopy (EIS)potentiodynamic curvesAcero galvanizadoCristales de cincCorrosión.Zinc galvanized steel sheets crystal size influence in environments containing chlorides and sulfatesInfluencia del tamaño del cristal de cinc de láminas de acero galvanizadas en ambientes que contienen cloruros y sulfatosinvestigationinfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a328http://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/access_right/c_abf245http://purl.org/coar/access_right/c_abf2Ramírez-Jerez, Julieth AndreaValero-Alvarado, MarioPeña-Ballesteros, Darío YesidTorres-Ramírez, Jhon Edisson001/14117oai:repositorio.uptc.edu.co:001/141172025-07-18 11:53:44.172metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co |

The composition and distribution of the products of corrosion (FeO and some zinc compounds) and the surface damage caused by them, were determined using XRD and SEM-EDS. Results showed that the degradation of the oxide layer formed is affected by the presence of chlorides, which penetrate reaching the surface of the base metal, producing localized corrosion. |
