Abstract

The poor dispersion stability and load-carrying properties of Gra may limit its further application in lubrication. The Gra/CNTs nanocomposite additive (abbreviated as GC) was successfully prepared in this paper. The micromorphology of Gra/CNTs was indicated that some carbon nanotubes were inserted into the interlayer of Gra layers. The different content of GC additive was added to hexadecane (C16). By comparison with that of pure C16, the average coefficient of friction (COF) of 0.3 wt% GC-C16 was reduced by 45 %, and its wear volume was also reduced by 43.75 %, which were attributed to the excellent interfacial load-bearing capacity of CNTs. The electric current-controlled COF of 1.0 wt% GC-C16 was decreased by 18 % compared to that of test without electric current. The electric current could break down the additive into finer structures, effectively bearing the load and repairing the worn surface. Therefore, GC nanocomposite additive acted as a remarkable role in the application of anti-friction area.

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.
