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. Nanofluids were characterized regarding both viscosity and stability. Tribological ball-on-flat tests were executed in presence of variably oriented magnetic field. The resulting orientation of nanorods within the contact zone influenced the friction coefficient with a maximum decrease of 22% with magnetic field oriented parallel to the sliding direction. The wear mechanism was investigated by means of SEM, X-EDS and Raman spectroscopy.
