Abstract:
We report the structural and tribological characterization
of nanostructured CNx thin films produced by the
deposition of a supersonic carbon cluster beam assisted by
nitrogen ion bombardment. The influence of the deposition parameters
on the chemical composition and structure of the films
has been systematically studied by X-ray photoelectron spectroscopy,
elastic recoil detection analysis, transmission electron
microscopy and atomic force microscopy. Depending on the deposition
parameters, the films show a structure ranging from
amorphous to disordered graphitic with interlinked planes. Nitrogen
content depends on the nitrogen ion kinetic energy. The
films have a very low density with a high surface roughness.
Friction measurements at the nanoscale show a correlation between
nitrogen content and mechanical properties of the system.
