Employment of the finite element method for determining stresses in coatings obtained on high-speed steel with the PVD process

The paper presents the possibility to employ the finite element method for evaluation of stresses in the Ti + TiN coating obtained in the magnetron PVD process on the sintered high-speed steel of the ASP 30 type, taking into account their deposition conditions. FEM was used to evaluate stress error in the simulated model. Computer simulation results were compared with the experimental results of stress measurement in the analysed coatings. 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.
