Purpose: The goal of this work is to determine residual stresses of coats obtained in PVD and CVD process with the use of finite elements method and comparative analysis with results obtained by laboratory investigations. Design/methodology/approach: Article introduces the usage of finite elements method for simulation of stresses measurement process in Ti/Ti(C,N)/CrN, Ti/Ti(C,N)/(Ti,Al)N, Ti/(Ti,Si)N/(Ti,Si) N, Cr/CrN /CrN, Cr/CrN/TiN and Ti/DLC/DLC coatings of the physical vapour deposition and chemical vapour deposition surface treatment performed on samples of heat treated cast magnesium alloy Modeling of stresses was performed with the help of finite element method in ANSYS environment, and the experimental values of stresses were determined basing on the sin2ψ. Findings: 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: The computer simulation results correlate with the experimental results. However for achieving better calculation accuracy in further researches it should be developed given model which was presented in this paper. Originality/value: From results of the simulation based on the finite element method is possible to compute the mechanical properties of coatings obtained in PVD process.
