The paper deals with the finite element simulation of coating subatrate systems and with test methods to determine matarial parameters like Young´s modulus of thin coatings. Two variants of nanoindentation of coating-substrate-systems were simulated. A penatration test, which incorporates the increase of the surface and the generation of free surfaces in bulk metal forming processes, is used to investigate the friction behaviour of the coating-substrate-system. Two numerical models of this penetration tests are compared with experimental results. The laser-wave measurment technique LAwave is introduced and the measured values of Young´s moduls for different coatings are presented.
