Analysis of tribological properties of lubricating gear oil with nano silica particles
Journal Title: Journal of Achievements in Materials and Manufacturing Engineering - Year 2016, Vol 79, Issue 2
Abstract
Purpose: Lubricants prepared with metal oxide nanoparticle additives are found to havebetter tribological properties. In this work the widely used commercial SN lubricating oil isadded with SiO2 nanoparticle and the tribological characteristics are studied. Wear testswere conducted on plain oil and oil with nanosized silica (SiO2) additives using a four balltribo-tester.Design/methodology/approach: The wear images of the ball specimens were analyzedusing confocal microscope to measure the topography of the wear parameters such as wearscar diameter, depth of wear, angle of the wear.Findings: It is found that the gear oil with silica nanoparticles is found to have improvedproperties. Results show a considerable reduction in the values of wear scar diameter, wearangle and wear depth for the gear oil added with SiO2 nanoparticles of 0.4 wt. %.Originality/value: In the work carried out, a new innovative technological approach toanalyze the tribological properties of lubricating oil by finding the wear scar diameter, wearangle and wear depth is reported.
