The present work reports the study of high-temperature corrosion of different alloys, such as AISI 310, AISI 316L e HAYNES® HR-120®, under oxidizing (air) and carburizing (CO/H2/CO2) atmospheres, by means of a crystal microbalance (EQCM). Conventional techniques, like EIS, SEM/EDX, XPS, XRD and RAIR, were used to characterize the corrosion products formed on the surface of bulk alloys after the thermal treatments. The followed approaches converge to indicate HR-120 as less susceptible to degradation, whereas AISI 316L as more reactive in both aggressive environments. Nonetheless, EIS results pointed out that the corresponding oxide grown in atmospheric air is less porous and more protective.

Abstract
The present work reports the study of high-temperature corrosion of different alloys, such as AISI 310, AISI 316L e HAYNES® HR-120®, under oxidizing (air) and carburizing (CO/H2/CO2) atmospheres, by means of a crystal microbalance (EQCM). Conventional techniques, like EIS, SEM/EDX, XPS, XRD and RAIR, were used to characterize the corrosion products formed on the surface of bulk alloys after the thermal treatments. The followed approaches converge to indicate HR-120 as less susceptible to degradation, whereas AISI 316L as more reactive in both aggressive environments. Nonetheless, EIS results pointed out that the corresponding oxide grown in atmospheric air is less porous and more protective.File | Dimensione | Formato | |
