Abstract
The foremost aim of the present work is to investigate the relationship between the thickness of the tribofilm formed and the tribological performance of palm oil based lubricant enriched by molybdenum disulphide (MoS2) nanoparticles. The experiment was carried out by pin-on-disk tribotester attached with electric contact resistance function conducted under boundary lubrication regime. The worn surface of specimen was characterized by scanning electron microscopy (SEM) coupled with energy dispersive X-ray spectroscopy (EDS) and surface profiler. The results indicate that PKO + MoS2 nanolubricant displayed a significant improvement in friction reduction and anti-wear performance; showing a 49.5% reduction in coefficient of friction and 46.1% wear scar diameter, compared to the base lubricant. Concurrently, the thickness of tribofilm was increased by 3.7% than that of base lubricant.
