Effect of copper-enriched layers on localized corrosion of aluminium-copper alloys

Copper-enriched layers were developed onto aluminum-copper alloys using alkaline etching in sodium hydroxide, for both, sputter deposited and bulk conditions. Enriched alloys were evaluated by potentiodynamic polarization in sodium chloride solution in order to determine the effect of the enriched l...

Se usaron aleaciones tanto depositadas por pulverización catódica, como vaciadas convencionalmente. Las aleaciones con las capas de enriquecimiento de cobre fueron estudiadas mediante polarización potenciodinámica en una solución de cloruro de sodio, para poder determinar si existe alguna correlación entre las capas de enriquecimiento de cobre y el potencial de picadura de las aleaciones. Los resultados no son concluyentes en el caso de las aleaciones depositadas por pulverización catódica; sin embargo, en el caso de la aleación en condición de vaciado, con el cobre en solución sólida, el potencial de picadura aumenta por la presencia de la capa de enriquecimiento, mostrando además una morfología diferente.application/pdfapplication/xmlengengUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ingenieria/article/view/8016/6460https://revistas.uptc.edu.co/index.php/ingenieria/article/view/8016/7184Copyright (c) 2018 María Ángeles Arenas-Vara, Peter Skeldon, Sandra Judith García-Vergarahttp://purl.org/coar/access_right/c_abf189http://purl.org/coar/access_right/c_abf2Revista Facultad de Ingeniería; Vol. 27 No. 48 (2018); 7-15Revista Facultad de Ingeniería; Vol. 27 Núm. 48 (2018); 7-152357-53280121-1129aluminium-copper alloysanodizingcopper enrichmentpittingaleaciones aluminio-cobreanodizadoenriquecimiento de cobrepotencial de picaduraEffect of copper-enriched layers on localized corrosion of aluminium-copper alloysEfecto de las capas de enriquecimiento de cobre sobre corrosión localizada en aleaciones aluminio-cobreresearchinvestigacióninfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a272http://purl.org/coar/version/c_970fb48d4fbd8a85Arenas-Vara, María ÁngelesSkeldon, PeterGarcía-Vergara, Sandra Judith001/14215oai:repositorio.uptc.edu.co:001/142152025-07-18 11:53:37.65metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co
