Composite films of nano-size nickel grains embedded in a nanocarbon (n-carbon) or amorphous carbon matrix were synthesized by a two source PVD evaporation process of C₆₀ fullerenes and Ni acetate.

The structure of the nanocomposite films were characterised by SPM methods, transmission electron microscopy (TEM), selected area electron diffraction (SAD), X-ray diffraction, chemical analysis and atomic force microscopy. Correlations with deposition parameters and typical structure changes are found. The Ni metallic component leads to bi-layered structures of the film and changes its mechanical properties comparing with the carbonaceous matrix properties. The tribological properties were studied using a HYSITRON Triboscope (electrostatic transducer) attached to a Scanning Force Microscope and controller Nanoscope IV. Single and multi-cycling indentation are used to study the depth dependent hardness and indentation modulus. Pop-ins reflects the layered nano-sturcture.
