摘      要：Graphite-like amorphous carbon film was fabricated by unbalanced magnetron sputtering *** spectroscopy,atomic force microscopy(AFM)and tribometer were subsequently used to investigate the microstructure and tribological properties of the resultant *** is found that the deposited carbon film is dominated by sp 2 sites,and the intensity ratio of the D and G peaks is as high as 4.0,which is one order of magnitude larger than that of diamond-like carbon films with high sp 3 content,indicating a more graphite-like ***,the as-deposited carbon film exhibits moderately high hardness(13.7 GPa),low internal stress(0.38 GPa)and superior tribological properties with high load bearing capacity(Hertz contact stress about 3.2 GPa)and low wear rate(2.73×10-10 cm3/N.m)in ambient *** it displays a poor wear resistance in water lubricated condition,a superior wear resistance is achieved in oil lubricated *** inherent physical property,the formation of transfer layer and the friction induced chemical reactions may be commonly responsible for its tribological properties.
