Abstract
The aims of this study were to determine the friction coefficient and the wear behaviour of palm fatty acid distillate (PFAD) using a four-ball tribotester, following the ASTM D-4172. In this paper, the normal load applied on the ball bearings varied from 40 kg to 120 kg. Experimental temperature was held constant at 75°C, while rotational speed was fixed at 1200 rpm. The test duration was one hour. Tests that were carried out using palm fatty acid distillate were conducted in exactly the same way using commercial hydraulic oil (HO) as a reference lubricant. The analyses focused on the friction coefficient and worn scar characteristic. Wear scar diameter was measured and the worn surface condition was observed using a high resolution microscope. Results showed that PFAD has a lower coefficient of friction than commercial hydraulic oil.
