Abstract: Nitrogen diffusion coefficients during the growth of nitrided concomitant layers produced by microwave post-discharge nitriding were estimated through an inverse problem model. Diffusion coefficients in each phase are estimated by setting the inverse problem associated with growth of compacts nitrided layer ƒ×¡¦-Fe4N1, austenite layer ƒ×, and a nitrogen diffusion zone in ferrite. The evolution of nitrogen concentration profile from supersaturated ferrite to the formation of compact nitride layers is described. Nitrogen concentrations in each phase and diffusion zone are not considered to be bounded by their solubility limits. Evolution for large periods (quasi-steady periods), coincides with layer growth evolution considered in mass balance models.
