Abstract:
In this paper, both the TiB 2 /SiC bilayer films and the carbon-doped TiB 2 (TiB 2 -C)/SiC bilayer films (SiC films as interlayer) were successfully deposited on quenched Cr12MoV steel substrate through magnetron sputtering technology, and the carbon-doping effect on microstructure and friction/wear properties of TiB 2 films were investigated. The results show that the doped-carbon presented in manner of sp 3 C-C and sp 2 C-C bonds i.e. DLC (diamond-like carbon). As sliding against steel balls under dry frictional condition, the doped-carbon strongly decreased the friction coefficient of the films and the material transfer from the friction pairs to the films. At the same time, the doped-carbon reduced the wear rate of the films, the wear rate of the TiB 2 films and the TiB 2 -C films were both in the magnitude order of 10 −5 mm3 m −1 N −1 , this is due to more material transfer significantly adhered on TiB 2 films than on TiB 2 -C films.
