Purpose: The aim of the research is the computer simulation of the internal stresses in bilayer coatings Ti+TiN and Ti+Ti(C,N) obtained in the magnetron PVD process on the sintered high-speed steel of PM HS6-5-3-8 in working atmosphere including 100% N2, and 50%N250%CH4. Design/methodology/approach: The experimental values of stresses were determined basing on the X-ray diffraction patterns using method sin2Ψ and computer simulation of stresses was carried out in MARC environment, with the help of finite elements method. 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 MARC program. Research limitations/implications: It was confirmed that using of finite element method for estimating stresses in PVD coatings can be a way for reducing the investigation costs Results reached in this way are satisfying and in slight degree differ from results reached by experimental method. However for achieving better calculation accuracy in further researches it should be developed given model which was presented in this paper. Originality/value: Presently the computer simulation is very popular, what 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.
