In the PHD-work named above is worked out the production and characterization of superhard nanocomposites out of nc-TiN/a-nc-TiSix/a-Si3N4. For the production of the superhard layers was beside an existing P CVD (´Plasma Chemical Vapor Deposition´) an equipment for reactive sputtering built and additionally used. The characterization took place in chemical as well as also in physical sense. With the chemical analysis, the influence of oxygen-impurities was especially examined in the layers for their qualities. On the basis of lowest oxygen-concentrations in the layers, a considerable decrease of the plastic hardness was observed. Moreover, the thermal stability of the represented nanocomposites was examined and worked out in detail.
