Abstract

In the present study, a novel process of in-situ fabrication of graphene sheets on ultrananocrystalline diamond (UNCD) film with aid of Au layer catalyst was designed. An in-situ ultra strong CC bonds are formed in the graphene-diamond interface under the action of heating, which can decrease the friction coefficient of the film. Besides, the friction-induced formation of graphene nano-scrolls play a pivotal role in achieving an exceptionally low friction coefficient of 0.025 for annealed Au/UNCD film. The potential structural formation mechanisms and frictional mechanisms have been discussed in detail. The achievement in this work provides a novel insight into the in-situ fabrication of graphene-diamond structure in mechanical fields with outstanding low friction coefficient and anti-wear performance.

通过在滑动界面上原位形成石墨烯片实现金刚石薄膜的超低摩擦机理

本研究设计了一种借助金层催化剂在超纳米晶金刚石（UNCD）薄膜上原位制备石墨烯片的新工艺。在加热作用下，石墨烯-金刚石界面会形成超强 CC 键，从而降低薄膜的摩擦系数。此外，摩擦诱导形成的石墨烯纳米卷轴对退火金/UNCD 薄膜达到 0.025 的超低摩擦系数起到了关键作用。我们详细讨论了潜在的结构形成机制和摩擦机制。这项研究成果为在机械领域原位制造具有出色低摩擦系数和抗磨损性能的石墨烯-金刚石结构提供了新的视角。

期刊介绍： DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices. The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
