Abstract

In this work, the metal Ni-induced graphene/hydrogenated amorphous carbon (a-C: H) composite films were prepared by a direct current (DC) magnetron sputter deposition system using argon and acetylene to sputtering a single nickel target. By adjusting the content of the C₂H₂ in the gas mixture, the composite films with different microstructures and constituents were prepared. The surface morphology, microstructure, carbon bonding status, hardness, toughness, and tribological properties of the deposited films were systematically analyzed to explore the relationship between structure and properties with C₂H₂ gas flow ratio. The results indicated that the films were composite films consisting of graphene embedded in hydrogenated amorphous carbon film. The hardness of the films increased significantly with increasing C₂H₂ gas flow ratio due to the decrease in metallic Ni content in the films. And the decrease in friction coefficient was related to the generation of graphene induced by Ni in the films and the passivation of suspension bonds. Especially, the films deposited at 30 % C₂H₂ exhibited low friction coefficient and outstanding wear resistance, which provides guidance for further designing carbon-based solid lubricating films with excellent performances.

金属诱导石墨烯/a-C:H复合膜的生长及其摩擦学性能

本研究采用直流磁控溅射沉积系统，利用氩气和乙炔溅射单一镍靶，制备了金属镍诱导石墨烯/氢化非晶碳(a- c: H)复合薄膜。通过调节气体混合物中C2H2的含量，制备了具有不同微观结构和成分的复合膜。系统分析了沉积膜的表面形貌、微观结构、碳结合状态、硬度、韧性和摩擦学性能，探讨了C2H2气体流量比与膜结构和性能的关系。结果表明，所制备的薄膜是石墨烯嵌入氢化非晶碳膜的复合薄膜。随着C2H2气体流量比的增加，膜的硬度显著提高，这是由于膜中金属Ni含量的降低。摩擦系数的降低与薄膜中Ni诱导石墨烯的生成和悬浮键的钝化有关。特别是在30% C2H2条件下沉积的碳基固体润滑膜具有较低的摩擦系数和优异的耐磨性，为进一步设计性能优异的碳基固体润滑膜提供了指导。

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.
