Corrosion Resistance at High Temperature of NiCrAlY and NiCrFeNbMoTiAl Coatings Deposited by APS

The corrosion at high temperature in pipes used in steam generating equipment (boilers), has been recognized as a serious problem, that results in the pipes thinning and therefore the equipments failure. In the last decade there has been a rise in investigations involving protective coatings to help...

In the last decade there has been a rise in investigations involving protective coatings to help, in some way to extend the useful life of these equipments. This investigation determined the NiCrFeNbMoTiAl and NiCrAlY coatings behavior, deposited by plasma-assisted thermal projection spraying (APS) on the alloy SA213 T22 (2¼Cr -1Mo), in acorrosive environment of 80 % V2O5- 20 % K2SO4 to 800 °C. The kinetics corrosion values were determined by linear polarization resistance (LPR) and electrochemical impedance spectroscopy (EIS). The results obtained show a lower kinetic corrosion on the NiCrFeNbMoTiAl coating than the NiCrAlY coating, confirmed by the SEM, Scanning Electron Microscopy.La corrosión a alta temperatura de las tuberías utilizadas en equipos generadores de vapor (calderas) ha sido reconocida como un grave problema que trae consigo el adelgazamiento de éstas y, por consiguiente, la falla de los equipos. En la última década se han incrementado las investigaciones que involucran recubrimientos protectores que ayudan de alguna manera a prolongar la vida útil de estos equipos. Esta investigación determinó el comportamiento de los recubrimientos NiCrAlY y NiCrFeNbMoTiAl depositados por proyección térmica asistida por plasma (APS) sobre la aleación SA213 – T22 (2¼Cr – 1Mo), en un ambiente corrosivo de 80%V2O5–20%K2SO4 a 800°C. Los valores de la cinética de corrosión fueron determinados mediante resistencia a la polarización lineal (RPL) y espectroscopia de impedancia electroquímica (EIE). Los resultados obtenidos muestran una menor cinética de corrosión en el recubrimiento NiCrFeNbMoTiAl que la presentada por el recubrimiento NiCrAlY, corroborado por Microscopia Electrónica de Barrido (MEB).application/pdftext/htmlspaspaUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ingenieria/article/view/3155/2847https://revistas.uptc.edu.co/index.php/ingenieria/article/view/3155/4342Revista Facultad de Ingeniería; Vol. 24 No. 38 (2015); 21-27Revista Facultad de Ingeniería; Vol. 24 Núm. 38 (2015); 21-272357-53280121-1129hot corrosionelectrochemicalcoatingsAPSCorrosión a alta temperaturaElectroquímicaRecubrimientosAPSCorrosion Resistance at High Temperature of NiCrAlY and NiCrFeNbMoTiAl Coatings Deposited by APSResistencia a la corrosión a alta temperatura de recubrimientos NiCrAlY y NiCrFeNbMoTiAl depositados por APSinvestigationinfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a491http://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/access_right/c_abf408http://purl.org/coar/access_right/c_abf2Tristancho-Reyes, José LuisChacón-Nava, José GuadalupeAlmeraya-Calderón, Facundo001/14103oai:repositorio.uptc.edu.co:001/141032025-07-18 11:53:58.259metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co
