Effect of hBN/MoS2 hybrid nanofluid minimum quantity lubrication on the cutting performance of self-lubricating ceramic tools when machining AISI 4340
Difficult-to-machine materials have consistently limited the improvement of machining efficiency. To address this challenge, this study proposes a strategy of combining Al2O3/SiC/G self-lubricating ceramic tools with hBN/MoS2 hybrid nanofluids. The experiment evaluates the ratio and concentration of the hBN/MoS2 hybrid nanofluid based on cutting forces, friction coefficients, cutting temperatures, surface roughness, and tool wear. Results show that better lubrication is achieved by hBN/MoS2 hybrid nanofluids compared to single nanofluids. The optimal hBN/MoS2 mixing ratio and nanofluid concentration are 2:1 and 1.5 wt%, respectively. Finally, the cutting lubrication mechanism and the synergistic mechanism of self-lubricating ceramic tools with hybrid nanofluids were proposed.
期刊介绍：
Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International.
Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
