Abstract

In this study, a new method for producing a composite material composed of epoxy resin and 0.03 wt% modified graphene oxide (MLGO) was developed and tested, where the MLGO was concentrated near one surface of the composite using a magnetic field. This feature reduced the wear rate of that surface by 87 % compared to pure epoxy resin and by 17 % compared to the uniform distribution of MLGO in the epoxy matrix. Concentrating MLGO near the surface proved to be the most effective strategy for improving wear resistance, as it also prevented crack formation. Moreover, the MLGO nanofiller not only enhances mechanical properties and wear resistance but also imparts magnetic sensitivity and luminescence, making it a valuable component for advanced materials.

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
