Experimental Study on the Effect of Different Speed Using Pin on Disc Tribotester

Abstract

Problems during interaction between two metal contact surfaces when friction, wear and excessive heat occurred. This interaction between two surfaces of moving parts of the metal have to be controlled by lubrication flow whose function to reduce friction and wear, prevent oxidation and also corrosion on the metal surface contact. The effect through this problem, it will decrease life of each component and economic wasted. The purpose of this paper is to investigate wear rates and friction force on sliding surfaces, wear scar diameter with different lubricating oil. This paper evaluates using a pin on disc tribotester according to the ASTM G99-95a.The results show RBD palm olein is lower than hydraulic oil for coefficient friction and wear scar diameter lubricated with RBD palm olein lower at low and high speed compared to the hydraulic oil. As a conclusion, RBD palm olein has better performance properties in terms of friction reduction (coefficient of friction) and wear resistance (anti-wear properties) at low and high speed. Therefore, RBD palm olein has possibility to use as a lubricant of mating components.
