摘要: This paper reports that DLC (diamond like carbon)/Ti and films were prepared by using pulsed laser arc deposition. R-ray diffraction, Auger electron spectroscopy, Raman atomic force microscopy, nanoindenter, spectroscopic ellipsometer, surface profiler micro-tribometer employed to study the structure tribological properties of DLC/Ti films. The results show film, with I(D)/I(G) 0.28 corresponding 76% sp3 content calculated uniform chemical composition along depth direction, 98 at% carbon, hardness 8.2 GPa Young's modulus 110.5 GPa, compressive stress 6.579 thickness 46 nm, coefficient friction 0.08, critical load 95mN, exhibits excellent mechanical properties.
