| Outline of Final Research Achievements |
Ion material process including ion implantation is significant on preparation of functional hard coating materials. Firstly, electrically conductive diamond-like carbon (DLC) films were prepared via plasma-based nitrogen ion implantation. It was examined that the electrical resistivity of the film markedly decreased with the increase in the implantation time. Then, the multi-process of DLC film deposition and subsequent nitrogen ion irradiation was performed. The prepared films had a resistivity of 30 mΩcm. Silicon-doped DLC films were also prepared by a reactive high-power impulse magnetron sputtering combined with a plasma-based ion implantation system. The resistivity of the films markedly increased from 3 to 380 Ωcm with the increase in the Si content.
Moreover, TiSiN and TiCN films were also prepared by high-power pulsed sputtering system. TiSiN film had a peak hardness of 43 GPa and the hardness of TiCN film reached 33 GPa.
