Tribological Evaluation of Turbostratic 2D Graphite as Oil Additive: A Recent Study| Chapter 1 | New Trends in Physical Science Research Vol.4

This research used powder technique to make Fe-SiC composites. SiC particles operate as precursors, causing a significant amount of turbostratic graphite to be distributed throughout the composite matrix. The temperature and composition range for stabilising the graphite phase in iron with a high yield were determined using Thermo-Calc® software. The recovered turbostratic 2D graphite particles were mixed in mineral oil to see if they might be used as a lubricating oil additive. The structure and morphology of the extracted graphite were studied using Raman spectroscopy and transmission electron microscopy (TEM), demonstrating the extremely disordered nature of turbostratic graphite. The friction coefficient and wear rate of a tribological pair were reduced when compared to pure mineral oil and mineral oil with commercial graphite particles added. There is limited contact between these atomic planes in turbostratic 2D graphite due to the misorientation and increase in interplanar distances, resulting in a low friction coefficient and decreased wear rate.
