Abstract

This Final Year Project outlines the background of the project “Determination of Wear Metals in Automotive Lubricating Oils Using UV Spectrometry”. Wear metals exist when frictional wear occurs during the relative motion between lubricated surfaces. The ball bearings were immersed in two different lubricant condition; engine oil and nanoparticle-enhanced engine oil. Each tests were conducted under varying load and speed, with 100, 300, 500 N and 100, 300, 500 rpm respectively. The tests were undergone under different temperature which 27, 50, and 100˚C and the running time was approximately 60 minutes. The nano oil was prepared by dispersing a mixture of approximately composition 0.5 vol.% of 70nm hexagonal boron nitride, hBN with SAE 15W-40 engine oil as base oil. The mixing method used was sonication technique. The investigation was carried under different parameters in order to differentiate the stability of used oil with and without nanoparticle enhanced of hBN at different parameter by using UV spectrometry method and to propose standard range of wavelength for metals disperse in lubricating oils by using UV spectrometry method.
