Article: Synthesis and tribological properties of TiC micro and nanoparticles Journal: International Journal of Surface Science and Engineering (IJSURFSE) 2015 Vol.9 No.1 pp.69 - 80 Abstract: The TiC micro and nanoparticles were successfully synthesised via immersing Ti3AlC2 powders in hydrofluoric acid assisted solvothermal reaction method. The as synthesised products are characterised by X-ray diffractometer, scanning electron microscopy and transmission electron microscopy. The results indicated the TiC compounds had micro and nano structures with the size range of 0.1 to 1 µm. The tribological properties of TiC micro and nanoparticles as additives in 100 SN base oil were investigated by UMT-2 ball-on-disc tribotester. The wear scars were measured by a common optical microscope and scanning electron microscopy. The study shows that under the determinate conditions, the friction coefficient of the base oil containing 1 wt% TiC micro and nanoparticles is lower than that of the pure base oil. A combination of rolling friction, and stable tribofilm on the rubbing surface could explain the good friction and wear properties of TiC micro and nanoparticles as additives.

The tribological properties of TiC micro and nanoparticles as additives in 100 SN base oil were investigated by UMT-2 ball-on-disc tribotester. The wear scars were measured by a common optical microscope and scanning electron microscopy. The study shows that under the determinate conditions, the friction coefficient of the base oil containing 1 wt% TiC micro and nanoparticles is lower than that of the pure base oil. A combination of rolling friction, and stable tribofilm on the rubbing surface could explain the good friction and wear properties of TiC micro and nanoparticles as additives.
