Improvement of abrasive wear resistance of the high chromium cast iron ASTM A-532 through thermal treatment cycles

High-Chromium White Cast Iron is a material highly used in mining and drilling shafts for oil extraction, due to its high wear resistance. However, because of the austenitic matrix found in the as-cast state, an adequate heat treatment cycle is necessary. This paper studies the effects of different...

However, because of the austenitic matrix found in the as-cast state, an adequate heat treatment cycle is necessary. This paper studies the effects of different cooling media after a destabilization treatment on the microstructure, hardening and abrasion resistance behaviors of a hypoeutectic high chromium white cast iron. The results show that although air cooling followed by immersion in CO2 can effectively reduce the retained austenite, this is not enough to transform completely the retained austenite into martensite. The low retained austenite percentages improve bulk hardness, but they decrease the abrasion resistance of the high chromium cast iron. The best combination of hardness and wear resistance was found in the samples cooled in air, due to the percentage of retained austenite and a moderate precipitation of chromium carbide.Las fundiciones blancas de hierro al alto cromo son muy usadas en la minería y en la perforación de pozos petroleros, debido a su alta resistencia al desgaste, sin embargo, debido a que en el estado de colada su microestructura es austenítica, es necesario someterlas a un adecuado ciclo de tratamiento térmico. Este trabajo estudia los efectos de los diferentes medios de enfriamiento después de un tratamiento de desestabilización de la microestructura y, por ende, el efecto del grado de endurecimiento sobre el comportamiento a la abrasión de una fundición blanca al alto cromo hipoeutéctica. Los resultados muestran que a pesar de que el enfriamiento al aire, seguido por inmersión en CO2, puede reducir eficazmente la austenita retenida, esto no es suficiente para transformarla completamente en martensita. El bajo porcentaje de austenita retenida incrementa la dureza del material, pero disminuye la resistencia a la abrasión de las fundiciones al alto cromo. La mejor combinación de dureza y resistencia al desgaste se encontró en las muestras enfriadas al aire, debido al porcentaje de austenita retenida y a una moderada precipitación de carburos de cromo.application/pdftext/htmlengengUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ingenieria/article/view/4141/3577https://revistas.uptc.edu.co/index.php/ingenieria/article/view/4141/5045Revista Facultad de Ingeniería; Vol. 25 No. 41 (2016); 93-103Revista Facultad de Ingeniería; Vol. 25 Núm. 41 (2016); 93-1032357-53280121-1129high chromium white cast ironHCWCIwhite cast ironchromium carbideshardnesswear testingaustenitemartensiteHCWCIfundiciones blancas de hierrofundición al alto cromocarburos de cromoaustenitamartensitaImprovement of abrasive wear resistance of the high chromium cast iron ASTM A-532 through thermal treatment cyclesMejoramiento de la resistencia al desgaste abrasivo de la fundición al alto cromo ASTM A-532 a través de ciclos de tratamiento térmicoinvestigationinvestigacióninfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a308http://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/access_right/c_abf225http://purl.org/coar/access_right/c_abf2Higuera-Cobos, Oscar FabiánDumitru, Florina-DianaMesa-Grajales, Dairo Hernán001/14138oai:repositorio.uptc.edu.co:001/141382025-07-18 11:53:44.104metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co
