Abstract

Friction consumes 33–50 % of global primary energy, causing about 80 % of mechanical fail. Therefore, reducing friction is vital for save energy and extending service life. Diamond-like carbon (DLC) films have broad industrial prospects due to their low friction coefficient and high wear resistance. This article discusses the state and challenges in tribology of DLC films, focusing on how their structure and external conditions affect tribological mechanisms. Firstly, the article discusses how deposition process affects the tribological properties. Subsequently, the influence of external factors on the tribological properties is discussed. Additionally, the article covers recent advances in molecular dynamics and first-principles calculations, crucial for understanding the micro and nanoscale tribological mechanisms. Finally, Summarizing current DLC film tribology research, the article outlines future research priorities and directions.

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.
