Modelling nitriding of iron: From thermodynamics to residual stress
The present article presents a few selected aspects of the modelling of gaseous nitriding of
pure iron. After descriptions of the thermodynamics of the gas phase and the reactions at the gas/solid
interface, a model description of the thermodynamics of
is given, which
takes the long-range ordering of nitrogen atoms into account. Subsequently, the kinetics of nucleation
and growth of iron nitride layers is described in terms of the rates of the surface reactions and solid
state diffusion. Thereafter, the mechanisms of stress generation in
layers during
nitriding are summarized. Finally, the model for stress development in
layers is
compared with published experimental work
