Abstract

Graphene oxide (GO)-reinforced NiCo composite coatings were fabricated on medium carbon steel substrates using a pulse electrodeposition technique with electrolytic solutions containing varying GO concentrations. The effect of GO concentration on the morphology, nano-hardness, elastic modulus, friction, and wear resistance of the coatings was systematically investigated. The incorporation of GO significantly improved the mechanical and tribological properties of the coatings. At an optimal GO concentration of 100 mg/L, the coatings exhibited the highest nano-hardness (6.15 GPa), elastic modulus (223 GPa), and the lowest friction coefficient (~0.21), along with a 65 % reduction in wear rate compared to pure NiCo coatings. These improvements are attributed to grain refinement, enhanced interfacial bonding, and the formation of a tribo-protective film. This study highlights the potential of Ni-Co-GO composite coatings for applications requiring high wear resistance and load-bearing capacity, such as automotive ball joint bearings.

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.
