Abstract
Friction, wear and fatigue are the three most commonly encountered industrial problems leading to the replacement of components and assemblies in an engineering system. The present paper experimentally investigated the effect of sliding speed on friction and wear behaviour of an aluminium pin sliding against a SKD11 disc with a constant normal load of 4 kg, lubricated with double fraction palm olein (DFPO) as a test lubricant and commercial hydraulic oil (HO) as a reference lubricant. Experiments were carried out at various sliding speeds from 900rpm to 1800rpm. The experimental works were carried out at room temperature. After the testing was completed, the friction coefficient and wear rates were calculated. The morphology of the worn surface was observed using a charge couple device (CCD) camera. Results showed that the friction coefficient for both lubricants decreased with increments in sliding speed.
