This detailed the tribological and tribochemical properties of magnetite (Fe3O4) nanoflakes used as additives in #40 base oil in a four-ball tribo-tester. The average friction coefficient of the friction pair for lubricant containing the Fe3O4 nanoflakes of 1.5wt% as a lubricant additive in the base oil is decreased by 18.06% compared to that of solely base oil. The chemical composition of base oil...
This paper presents experimental results on weakly magnetic field-assisted synthesis of magnetite (Fe 3 O 4 ) nano-particles in an oxidative co-precipitation method, in comparison to the case without magnetic induction. The XRD results show that a weakly magnetic induction below 220Gs could accelerate the phase transformation from goethite (α-FeOOH) to magnetite (Fe 3 O ...
