Abstract

This study focused on the effect of the temperature on the nanoparticles stability properties. This is due to the nature of the nanoparticle where it easily to aggregate when hydrated. The nanoparticles also have a suspension or sedimentation problem when it been added in the lubricant as an additive. An experimental procedure was conducted to identify the effect of difference temperature in homogenize the conventional engine oil SAE 15W40 grade mixed with nanoparticles as Nano-oil sample. A set of temperatures were used in this experiment started at room temperature 30°C, 40°C and 70°C. The absorbance values of the nano-oil sample were measured by using UV-spectrometer as quantitative results. The samples also was observed periodically by capturing the image of the Nano-oil as a qualitative result. The nanoparticles used in this study were hexagonal boron nitride (hBN), alumina (Al2O3), and zirconia (ZrO2). The stability of the nano-oil with hBN, Al2O3 and ZrO2 nanoparticles much better at temperature 70°C. Nano-oil with ZrO2 nanoparticles showns dispersion well at every temperature. Futhermore, it was still stabled up to two months even though was left at room temperature compare to other samples containing hBN and Al2O3 nanoparticle.
