| 英文摘要 | By choosing carbide-forming element cr and non-carbide-forming element cu as co-doped metal elements, we firstly fabricated cu and cr co-doped diamond-like carbon (cu/cr-dlc) films using a facile hybrid ion beam deposition system. the effect of cu/cr co-doping on wettability and mechanical properties of dlc films were focused. the resultant cu/cr-dlc films were shown to afford good hydrophobicity and superior mechanical performance. in particular, the film with cu11.88%cr6.57% (at.%) exhibited a relatively high water contact angle of 103.6, lower residual stress of 0.89 gpa and high hardness of 13.44 gpa. the combined structural analysis demonstrated that the synergistic cu/cr co-doping resulted in the critical and significant relaxation of distorted c-c bond length, which ultimately caused the reduction in residual stress. due to the formation of hard cr carbide nano-particles in amorphous carbon matrix, the films maintained the high value of hardness. in addition, noted that the interesting wetting variety from hydrophilic to hydrophobic state was attributed to the enhanced surface graphitization and emergence of copper oxidation phases, and the film topographical microstructure could also promote the hydrophobicity of film when the maximum height of roughness was in a certain range. these results provide an expected robust synthesis method to make dlc film a promising protective coating for long lasting hydrophobic application and related harsh fields.
