Figures

Image of FIG. 1.
FIG. 1.

Pulsed laser deposition system. A graphite-metal composite target is ablated at room temperature, resulting in the formation of a diamondlike carbon-metal nanocomposite film.

Image of FIG. 2.
FIG. 2.

(a) -contrast dark field image of diamondlike carbon–titanium nanocomposite film FGTi2, (b) -contrast dark field image of diamondlike carbon–silver nanocomposite film FGAg1.

Image of FIG. 3.
FIG. 3.

(a) Electron energy loss near the carbon- edge of diamondlike carbon–silver nanocomposite FGAg1, (b) electron energy loss near the carbon- edge of diamondlike carbon–titanium nanocomposite FGTi2. The peak in the region from results from the excitation of electrons from the ground state to the vacant antibonding state. The peak in the region above results from the excitation of electrons from the ground state to the higher state.

Image of FIG. 4.
FIG. 4.

Visible Raman spectrum of diamondlike carbon–titanium nanocomposite film FGTi3. Diamondlike carbon-metal nanocomposite films exhibit greater asymmetry in the -band and a slight increase in the -band height.

Image of FIG. 5.
FIG. 5.

Load vs depth obtained from scratch testing of diamondlike carbon–titanium nanocomposite FGTi1. Cycles of abrupt up and down motion signify coating delamination ahead of the moving tip.

Image of FIG. 6.
FIG. 6.

Scratch result for diamondlike carbon–silver nanocomposite FGAg1 at normal load. The scratch tip had reached the substrate, and plastic deformation of the Ti–6Al–4V substrate was observed.

Image of FIG. 7.
FIG. 7.

Scratch result for diamondlike carbon–titanium nanocomposite FGTi1 at normal load. Forward chevron cracks in the scratch direction were observed at this load.
