The global manufacturing industry extensively employs petroleum-based oil as a metalworking fluid for lubrication during machining processes. Nevertheless, petroleum-based oil cannot naturally decompose, is not a sustainable resource, and has detrimental effects on human health and the environment. Hence, this research aims to investigate the viscosity and tribological properties of lubricant made from modified palm oil (MPO). The activated carbon (AC) and tungsten disulfide (WS2) nanoparticles have been incorporated into MPO at a concentration of 0.025 wt% and compared to synthetic ester (SE). The findings indicated that adding 0.025 wt% activated carbon to MPO (MPOa) resulted in enhanced tribological performance compared to SE and MPO. MPOa had a high VI at 303, with the lowest coefficient of friction (COF) and mean wear scar diameter (MWSD) values at 0.0628 and 607.1 μm. This improvement is due to AC nanoparticles forming a thin, stable, lubricating film during operation. MPOa surpassed other oil samples, thus making it an option for applications that required exceptional lubricating characteristics, less friction, and improved wear resistance.

摘要

The global manufacturing industry extensively employs petroleum-based oil as a metalworking fluid for lubrication during machining processes. Nevertheless, petroleum-based oil cannot naturally decompose, is not a sustainable resource, and has detrimental effects on human health and the environment. Hence, this research aims to investigate the viscosity and tribological properties of lubricant made from modified palm oil (MPO). The activated carbon (AC) and tungsten disulfide (WS2) nanoparticles have been incorporated into MPO at a concentration of 0.025 wt% and compared to synthetic ester (SE). The findings indicated that adding 0.025 wt% activated carbon to MPO (MPOa) resulted in enhanced tribological performance compared to SE and MPO. MPOa had a high VI at 303, with the lowest coefficient of friction (COF) and mean wear scar diameter (MWSD) values at 0.0628 and 607.1 μm. This improvement is due to AC nanoparticles forming a thin, stable, lubricating film during operation. MPOa surpassed other oil samples, thus making it an option for applications that required exceptional lubricating characteristics, less friction, and improved wear resistance.
