SUMMARY
Models for simulation of processes of surface treatment have been presented in the article. Nitriding process
has been used as an exemplar. The models consist of:
1) heuristic models to define the composition of nitriding atmosphere on the base of the assumed course of the changes of the temperature and nitriding potential during the process,
2) artificial neural network to predict profiles of micro-hardness for given process parameters,
3) evolutionary algorithms to foresee the process parameters for the given profile of hardness. The models of very
good performance were achieved. Graphical user interface (GUI) has been created for easy use of the models.
Designed models are combined and integrated in software package that is built up on a modular fashion. The
exemplars of the application of the models are given, to demonstrate that they are convenient and powerful
tools in surface engineering.
