    The preparation of nanostructured (nanocomposite or nanocrystalline) diamond coatings is studied due to their extreme mechanical hardness and wear resistance, high bulk modulus, low compressibility, high thermal conductivity, low thermal expansion coefficient , broad optical transparency from the deep ultraviolet to the far infrared, high electrical resistivity, biocompatibility, etc. Their main advantage compared to the polycrystalline diamond film is, that they can be prepared with relatively low surface roughness. The mechanical properties such as hardness, fracture toughness, film-substrate adhesion and thermomechanical stability of the coating-substrate system play always a crucial role for industrial applications of the coatings. Therefore the main aim of the present work is to study the mechanical properties of ultrananocrystalline thin films using two different indentation techniques.
