Notes:
Amorphous Ti/C multilayers were prepared on titanium-alloy and silicon (100)-wafersubstrates by pulsed laser deposition. Films with different Ti concentration were synthesized bychanging the ablating time for Ti and C targets. The morphology and microstructure of Ti/Cmultilayers were characterized by scanning electron microscopy (SEM), Raman spectroscopy andX-ray diffraction (XRD). Both of the Ti and C monolayers were amorphous. The metallic Tistimulated the formation of more amorphous carbon phase by reducing the sp2 aromatic bonds andelongating the C-C chain bonds. The tribological properties of Ti/C multilayers were investigatedby ball-on-disk tribometer. The pure C film and the multilayers containing more than 68.8 at.% ofTi showed low wear resistance. The multilayer contained 36.8 at.% of Ti exhibited the lowest wearrate at 3.54×10–16 m3/N·m. The formation of carbon related interlayer and its effect on tribologicalperformance of the films were discussed
