Notizen: g (t)=g 0 f -1 (t/t 0), where g(t) is the sub-layer thickness at time t, g 0 and t 0 are parameters which depend on the treated material and plasma characteristics, f -1 is the inverse of the function −ln(1−x)+x), 0≤x≤1. Under negligible erosion effects, the expression for g(t) reduces to the parabolic law. The diffusion zone (substratum) growth does not follow the parabolic law as well. However, the deviation occurs after long plasma nitriding time. The model can be used for experimentally determining the effective diffusion coefficients and the erosion rate during plasma nitriding of metal surfaces.
