Abstract
The present work is focused on the development of a hybrid nano-lubricant with improved tribological properties by mixing molybdenum-disulphide (MoS2) nanoparticles with alumina nanoparticles in oil-water emulsion base fluid in a fixed volumetric proportion (10:90). The tribological testing and contact angle measurement of prepared lubricants have been performed on pin-on-disc tribometer and goniometer, respectively. The hybrid lubricant has shown better results compare to base fluid (oil-water emulsion) and alumina-based monotype lubricant. Furthermore, the test results confirm the reduction in wear and coefficient of friction with increase of nanoparticle concentration. Moreover, the performance of hybrid nanofluid has been evaluated in terms of machining response using minimum quantity lubrication (MQL) technique on turning of AISI 304 steel. The addition of hybrid nanoparticles significantly reduces the tool flank wear as compared to monotype nano-lubricant and base fluid.
