Effect of external magnetic field on tribological properties of goethite (a-FeOOH) based nanofluids

摘要

Additives responsive to magnetic fields can be easily manipulated under the action of external stimuli and employed in various sectors, with great feasibility. In this work, suspensions of goethite nanorods were developed for anti-friction and anti-wear purposes. Goethite represents a promising additive in lubricants promoting the formation of a protective tribofilm during rubbing processes, especially under severe lubrication regime.
