En esta investigación se evaluó el comportamiento ante el ataque por corrosión a alta temperatura en el recubrimiento NiCrFeNbMoTiAl, aplicado por rociado térmico asistido por plasma con arco no transferido sobre una aleación T22 (2¼Cr – 1Mo), al exponerse a un agente corrosivo de 80%V2O5 – 20%Na2SO4 en un rango de temperatura comprendido entre 700°C a 900°C. Los valores de densidades de corrosión y velocidades de corrosión fueron determinados mediante espectroscopia de impedancia electroquímica (EIE). Los resultados obtenidos mostraron un aumento en la velocidad de corrosión al aumentar la temperatura de ensayo.Downloads
