This research investigates the effect of adding copper oxide nanoparticles to the oil Gr-6004 base fluid and its concentration changes on the surface roughness of gudgeon pin and the thermal conductivity of the nanofluids during the superfinishing process. The results show that adding nanoparticles significantly reduces the surface roughness and increases the thermal conductivity. Increasing the concentration of nanoparticles further decreases the roughness and increases the thermal conductivity. Dispersing CuO nanoparticles into the base fluid also reduces the oil temperature.
This research aims to investigate the effect of adding copper oxide nanoparticles to the oil Gr-6004 base fluid and its concentration changes from 0.1% to 0.4% on the surface roughness of gudgeon pin and the thermal conductivity of the nanofluids during the superfinishing process. The main novelty of this investigation is analyzing the impact of utilizing CuO/oil Gr-6004 nanofluid on thermal conductivity of oil and surface quality of gudgeon pin during superfinishing process. Based on the results, adding nanoparticles to the oil Gr-6004 has significantly reduced the surface roughness. In addition, by increasing the concentration of nanoparticles to 0.4%, the surface roughness has decreased by 57% compared to oil Gr-6004. Also, by adding nanoparticles, the thermal conductivity of the nanofluids has increased to 19.5%. In addition, dispersing CuO nanoparticles into base fluid reduces oil temperature by 17.44%.
