Popis Diamond-like carbon films (DLC) exhibit useful properties such as high hardness, low friction coefficient, high thermal conductivity and wide band gaps. However, due to an inherent internal stress and bad adhesion to stainless steel their use in industrial applications is limited. A better adhesion can be achieved by adding different dopants into a DLC matrix, especially for metallic substrates. Also, silicon based interlayers was used In order to promote the adhesion. Hydrogenated DLC films using different mixtures were prepared by plasma enhanced chemical vapor deposition (PECVD) using capacitively coupled rf discharge at 13.56 MHz. Optical and mechanical methods were used to to determine functional properties. The hardness and Young's modulus of multilayered films were between 14 GPa and 80 GPa, respectively. For adhesion, the critical load Lc2 ranged from 2.1 N in the case of nitrogen containing DLC, to 11.8 N for multilayered film based on SiOx.
