    Nanocrystalline titanium carbide embedded in an hydrogenated amorphous carbon matrix (nc-TiC/a-C:H)shows high hardness and Young’s modulus together with low friction coefficient. In this paper, we report on the preparation of well adherent (nc-TiC/a-C:H)coatings - 5mm thick on stainless steel substrates using a well balanced magnetic field configuration and only very low power RF bias on the substrate. Hardness and Young’s modulus of this coatings are 43 Gpa and 380 Gpa, respectively. The mechanical properties – hardness and Young’s modulus – measured from the coatings top reach the values obtained at optimized experiments where the unbalanced magnetic field configuration was used. A simple method of depth profiling suitable for evaluation of mechanical properties of several micrometers thick coatings is developed and employed. The paper reports on the depth profile analyses of the coating hardness, Young’s modulus, composition and morphology.
