Four ionic liquids containing dithiocarbazate were synthesized. Their antiwear and friction-reducing properties of these synthetic liquid compounds as the lubricants of a steel/steel contact were examined using an Optimol SRV oscillating friction and wear tester in ambient condition. The results indicated that the ionic liquids containing dithiocarbazate as the lubricants showed excellent friction-reducing and antiwear properties for the steel/steel pair. The introduction of the dithiocarbazate group into the molecules of the ionic liquids contributed to improve the tribological behaviour.

This paper used graphite nanoparticles with the diameter of 35 and 80 nm and LB2000 vegetable based oil to prepare graphite oil-based nanofluids with different volume fractions by two-step method. The tribological properties of graphite nanoparticles as LB2000 vegetable based oil additive were investigated with a pin-on-disk friction and wear tester. Field emission scanning electron microscope (FE-SEM) and energy dispersive spectroscopy (EDS) were used to examine the morphology and the content of some typical elements of wear scar, respectively. Further, the lubrication mechanism of graphite nanoparticles was explored. It was found that graphite nanoparticles as vegetable based oil additive could remarkably improve friction-reducing and antiwear properties of pure oil. With the increase of volume fraction of graphite nanoparticles, the friction coefficient and the wear volume of disk decreased. At the same volume fraction, the smaller particles, the lower friction coefficient and wear volume. The main reason for the improvement in friction-reducing and antiwear properties of vegetable based oil using graphite nanoparticles was that graphite nanoparticles could form a physical deposition film on the friction surfaces.
