| 中文摘要 | Diamond-like carbon (DLC) films were prepared in a pulsed-DC discharged CH4/Ar plasma. Effects of duty cycle ([ton/(ton+toff)]×100%) on the composition and properties of DLC films were investigated. In general, the increased duty cycle led to an up-shift of the G peak position, an increase in the ID/IG and sp2 /sp3 ratio, and a reduction of the number of C–Hbonds and the filmhardness, revealing a graphitization tendencywith increasing duty cycle. Tribologically, ultralow and steady friction coefficients (0.005 and 0.008) in dry nitrogen atmosphere were obtained for the films prepared under a duty cycle of 50% and 65%. The unique mechanical property and chemical nature brought by the moderate sp2 /sp3 ratio and the proper H content were considered to be responsible as the films deposited in this duty cycle range could simultaneously provide the high chemical inertness and the ultrasmooth sliding surfaces required for achieving ultralow friction. In addition, the structure was less vulnerable towatermolecules in the case of stewing. The diamond-like nature and the ultralowfriction performance were hardly affected even experiencing a 4-month immersion in water. |
