Presentation Title Conditions for Exclusive External Scale Formation in the High Temperature Oxidation of Alloys
Author(s) Karl Sieradzki, William Blades, Elizabeth Opilia
On-Site Speaker (Planned) Karl Sieradzki
Abstract Scope Within the context of Wagner’s oxidation theory, the conditions for exclusive external scale formation are examined using a recursive-sequence approach which has a fixed-point defining the critical mole fraction of the passivating component in a binary single-crystal alloy. These results highlight the importance of lateral growth of oxide particles. Next, a thin-film growth analogy for a kinetic model of exclusive external scale growth is described. This model is presumed to be operative during transient oxidation. The unknown parameters required to test the usefulness of this approach includes the surface/interfacial diffusivities of oxygen species as well as that of the scale forming component and the magnitude of Ehrlich-Schwoebel barriers. Even lacking these results, the analysis shows that for a large enough nucleation density of oxide particles, exclusive external oxide scales should form.
