The aim of the work reported here is to evaluate the effect of the substrate on the hardness measurements of thin hard coatings. The nanoindentation process was simulated by using the finite element method (FEM). An axisymmetric model of the coating/substrate system with isotropic and homogeneous properties has been considered. The indenter has been simulated either as a rigid surface or as a diamond tip. The material properties calculated in a nanoindentation experiments were used for evaluating loading-unloading curves and the results were compared to measured values. The extension of the plastic deformation zone induced by a cone-shape indenter on a bulk TiN and on a TiN/HSS specimens was determined for an indentation depth equal to 35% of the film thickness.
