Tribological analysis of the neem oil during the addition of SiO2 nanoparticles at different loads

The pollution in the environment with the use of petroleum products is increasing at a faster rate. To overcome this problem, there is a need to search for an alternative. This study proposed neem oil as an alternative for tribological applications. This study involves silicon dioxide nanoparticles for the improvement of the lubricity of the oil. The process is accomplished on the DUCOM tribometer at various loads. The minimum coefficient of friction was obtained when nanoparticles are added up to 0.3 percent. During higher amount of nanoparticles addition, more wear of the disc occurs. At 0.3 percentage of nanoparticles, improved results in terms of wear of the parts have been observed with comparison to the raw neem oil. (C) 2020 Elsevier Ltd. All rights reserved.
