中文摘要:
      类金刚石(Diamond-like carbon,DLC)薄膜,具有高硬度、高化学惰性及低摩擦磨损等特性,特别是在一定条件下的超滑特性(摩擦系数低于0.01),为真正的近零摩擦和磨损的实现提供了可能性,因此在固体润滑领域展现出巨大的应用前景。从元素掺杂种类和键合结构特点,概述了DLC薄膜的种类多样性,归纳了不同DLC薄膜的力学及摩擦学特性。通过对比分析不同DLC薄膜在不同环境条件下的摩擦学行为,阐述了DLC薄膜超滑实现的环境敏感性,其中薄膜和环境中氢原子的作用十分关键,同时提出Si等元素掺杂改善超滑环境敏感性的可行方案。重点介绍了3种DLC超滑机理——界面钝化理论、界面石墨化理论以及转移膜形成理论,这三者均具有一定的局限性,如何更深入且全面认识DLC超滑仍是一个科学难题。最后强调了先进界面检测和表征技术对探秘DLC超滑态界面组成的重要性,并对今后亟需开展的深入研究方向进行了展望。
英文摘要:
      Diamond-like carbon (DLC) films have shown significant application prospects in the field of solid lubrication due to their high hardness, good chemical inertness, low friction and wear properties and especially the superlubricty (friction coefficient lower than 0.01) performance under some certain conditions, which can provide new opportunities for the realization of near-zero friction and wear. Various DLC films (DLCs) were summarized according to the differences in doped elements and bonding structures, and the corresponding mechanical and tribological properties were also overviewed. By comparing the tribological properties of DLCs under different environmental conditions, the sensitivity of DLCs’ friction to environmental atmosphere was mainly illustrated, where the hydrogen atoms in films and atmosphere played important roles. At the same time, a feasible scheme to improve the environmental sensitivity of superlubricity by doping Si element or other elements was proposed. Three kinds of DLCs’ superlubricity mechanisms were mainly introduced: surface passivation theory, graphitization theory and transfer film formation theory. All three mechanisms mentioned above had limitations in some extent, and it was still a scientific difficulty to systematically understand and explore the superlubricity mechanisms of DLCs. Finally, the importance of advanced characterization techniques for the detection of chemistry and microstructure of superlubric interface was emphasized, and further research directions were also proposed.
