Abstract

Abstract: Different nanoparticles exhibit various physicochemical properties (e.g., structure and shape), which can influence their lubricating properties. In this work, six nanofluids, namely, MoS2, SiO2, diamond, carbon nanotubes (CNTs), Al2 O3, and ZrO2, were used as minimum quantity lubrication grinding fluids to select the kind of nanoparticles with optimum lubrication performance in grinding nickel alloy GH4169. Experimental results concluded the following: 1) Nanoparticles with spherical or sphere-like molecular structure and nanofluids with high-viscosity demonstrate superior lubrication performances. 2) The polishing effect of nanodiamond particles enhances their surface morphology. 3) The lubricating property of the six nanofluids is described in the following order: ZrO2 2 2 2 O3 . Highlights: MQL grinding using different types nanofluids was experimental evaluated. The lubrication properties and corresponding mechanism of nanofluids was analyzed. The lubricating properties of Al2 O3 nanofluids is better than pure palm oil. The nanofluids physical properties and viscosity influence the lubricating property. The diamond nanofluid also contributes polishing to the grinding process.
