An X-ray diffraction study of corrosion products from low carbon steel
ABSTRACT: It was found in earlier work a decrease in the corrosion rate from low carbon steel when it was subjected to the action of a combined pollutant concentration (S04^~ = 10"^ M + Cl" = 1.5 X 10~^ M). It was also found that large magnetite content of the rust was related to higher co...

ABSTRACT: It was found in earlier work a decrease in the corrosion rate from low carbon steel when it was subjected to the action of a combined pollutant concentration (S04^~ = 10"^ M + Cl" = 1.5 X 10~^ M). It was also found that large magnetite content of the rust was related to higher corrosion rates. In the present study corrosion products are further analyzed by means of X-ray diffraction to account for composition changes during the corrosion process. It is found that lepidocrocite and goethite are the dominant components for the short-term corrosion in all batches considered while for log-term corrosion lepidocrite and goethite dominates if the corrosion rate is low and magnetite dominates if the corrosion rate is high. The mechanism for decreasing the corrosion rate is related to the inhibition of magnetite production at this particular concentration. |

También, se concluyó que altos contenidos de magnetita en la herrumbre estaban asociados a altas tasas de corrosión. En este trabajo se retoman estas herrumbres para analizarlas por difractometría de rayos X para tomar en cuenta los cambios en composición durante el proceso corrosivo. Se encuentra que goethita y lepidocrocita son las componentes dominantes durante la etapa inicial del proceso en todos los experimentos. En cambio para tiempos largos de exposición, y si la tasa de corrosión es alta, la magnetita es el producto de corrosión dominante. El mecanismo que reduce la tasa de corrosión, en la mezcla mencionada anteriormente, está relacionado con la inhibición del proceso de producción de la magnetita en estas condiciones.COL00996984application/pdfengConsejo Superior de Investigaciones Científicas; Centro Nacional de Investigaciones MetalúrgicasMadrid, Españahttp://creativecommons.org/licenses/by/2.5/co/https://creativecommons.org/licenses/by/4.0/info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2An X-ray diffraction study of corrosion products from low carbon steelEstudio por difracción de rayos X de los productos de corrosión del acero al carbonoArtículo de investigaciónhttp://purl.org/coar/resource_type/c_2df8fbb1https://purl.org/redcol/resource_type/ARThttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionDifracción de rayos XX-rays - diffractionAceroSteelEspectroscopía de MossbauerMossbauer spectroscopyIonesIonsSulfatosSulphatesCorrosiónCorrosionClorurohttp://aims.fao.org/aos/agrovoc/c_24011Rev.
