dc.description.abstract | El hierro dúctil (DI) puede modificar sus propiedades con la adición de elementos aleantes y tratamientos térmicos adecuados. En este trabajo se estudiaron los efectos del vanadio y molibdeno en la microestructura y resistencia a la corrosión del DI y el hierro dúctil austemperizado (ADI). La resistencia a la corrosión fue evaluada por la técnica de polarización potencio-dinámica en 0.5 M H2SO4, 0.5 M NaCl y 0.5 M NaOH como electrólito. El ADI aleado con vanadio presenta ausferrita gruesa formada por agujas gruesas de ferrita, mientras que la combinación de vanadio y molibdeno permite obtener una microestructura fina compuesta de ausferrita y agujas delgadas de ferrita; esta microestructura mejora la resistencia a la corrosión en NaCl y NaOH. El DI presenta corrosión debido al par galvánico entre los nódulos de grafito y la ferrita; sin embargo, la presencia de una gran cantidad de carburos incrementa su resistencia a la corrosión en H2SO4. | es_MX |

dc.description.abstractEnglish | Ductile iron (DI) can acquire various properties with the addition of alloying elements and through heat treatment. In this work, the effects of vanadium and molybdenum on the microstructure and corrosion resistance of DI and austempered ductile iron (ADI) were studied. Corrosion resistance was evaluated by potentiodynamic polarization techniques in 0.5 M H2SO4, 0.5 M NaCl, and 05 M NaOH as electrolyte. The ADI alloyed with vanadium presented an upper ausferritic microstructure consisting of broad ferrite needles, while the combination of vanadium and molybdenum allows obtaining a fine microstructure composed of ausferrite and thin needles of ferrite; this microstructure improves the corrosion resistance in NaCI and NaOH. The DI’s showed corrosion due to the galvanic pair between the graphite nodule and the ferrite; however, a high amount of carbide increases the corrosion resistance in H2SO4. | en |
