Abstract
In this paper, two nanofluids suitable for minimum quantity cooling and lubrication (MQCL) assisted turning of Ti 6Al 4V ELI are reported after a comprehensive study of 18 nanofluids. The nanofluids were prepared by adding three different nanoparticles (Al2O3, MoS2, and rutile-TiO2) to vegetable oils (canola and extra virgin olive oils) respectively, at three different concentrations (0.5, 2, and 4% vol). The use of canola nanofluid containing 0.5 vol% Al2O3 provided a superior surface finish; on the other hand, canola nanofluid enriched with 0.5 vol % MoS2 was found to be conducive to lowering T and increasing rc. Moreover, the nanofluids rendered an auspicious tool wear behavior and impeded attrition wear. Traces of tribofilm formation and the effect of nano-polishing…
