Turning of Inconel 825 with coated carbide tool applying vegetable-based cutting fluid mixed with CUO, Al2O3 and CNT Nanoparticles by MQL 2019-28-0060

Inconel 825 is nickel (Ni)-iron (Fe)-chromium (Cr) alloy with additions of copper (Cu), molybdenum (Mo), and titanium (Ti). The alloy has excellent resistance to corrosion and is often the most cost-effective alloy in sulphuric acid piping vessels and chemical process equipment. No attempt of applying MQL with the addition of nanoparticles was reported conferring to the works accessed. The present study is focused on evaluating the effect of the addition of nanoparticles (CUO, Al2O3 and CNT) in vegetable oil applied by MQL mode during turning of Inconel 825 with coated carbide tool. Cutting force, surface roughness and tool wear are evaluated. The results showed that the addition of nCNT substantially improved the machining performance, smaller flank and crater wear on the tool edge, while the adhesion and abrasion are observed as wear mechanism and better results are obtained at 0.5% of nCNT+ vegetable oil to produce the lowest values.
