The kinetic of high temperature oxidation of an AISI 304L steel was studied. Industrial samples were oxidized at different temperatures (ranging from 800 ° C to 1200 ° C) and in atmospheres with different oxygen content, using a TG instrument. The oxide layers produced after 3 hours of treatment were analyzed with SEM-EDS and XRD techniques in order to characterize the morphologies and the structures of the oxides. Modelling of the weight-versus- time curves was developed, leading to the calculations of activation energies and diffusion coefficients.

Abstract
The kinetic of high temperature oxidation of an AISI 304L steel was studied. Industrial samples were oxidized at different temperatures (ranging from 800 ° C to 1200 ° C) and in atmospheres with different oxygen content, using a TG instrument. The oxide layers produced after 3 hours of treatment were analyzed with SEM-EDS and XRD techniques in order to characterize the morphologies and the structures of the oxides. Modelling of the weight-versus- time curves was developed, leading to the calculations of activation energies and diffusion coefficients.File in questo prodotto:
