Purpose: The aim of the research is the computer simulation of the internal stresses in bilayer coatings Ti+Ti(CxN1-x) obtained in the magnetron PVD process on the sintered high-speed steel of the ASP 30 in working atmosphere including 75% N2 i 25% CH4, 50% N2 i 50% CH4, and 25% N2 i 75% CH4. Design/methodology/approach: Computer simulation of stresses was carried out in ANSYS environment, using the FEM method and the experimental values of stresses were determined basing on the X-ray diffraction patterns. Findings: The computer simulation results correlate with the experimental results. The presented model meets the initial criteria, which gives ground to the assumption about its usability for determining the stresses in coatings, employing the finite element method using the ANSYS program. Research limitations/implications: In order to evaluate with more detail the possibility of applying these coatings in tools, further computer simulation should be concentrated on the determination of other properties of the coatings for example - microhardness. Originality/value: Presently the computer simulation is very popular and it is based on the finite element method, which allows to better understand the interdependence between parameters of process and choosing optimal solution. The possibility of application faster and faster calculation machines and coming into being many software make possible the creation of more precise models and more adequate ones to reality.
