Assessment of Lubrication Property and Machining Performance of Nanofluid Composite Electrostatic Spraying (NCES) Using Different Types of Vegetable Oils as Base Fluids of External Fluid

Abstract The current study of minimum quantity lubrication (MQL) concentrates on its performance improvement. By contrast with nanofluid MQL and electrostatic atomization (EA), the proposed composite spraying (NCES) can enhance more comprehensively. However, it is largely influenced by base fluid external fluid. In this paper, property machining NCES different types vegetable oils (castor, palm, soybean, rapeseed, LB2000 oil) as fluids were compared evaluated friction milling tests under flow ratios internal fluids. electrowetting angle tested to analyze influence oil type performances. test results show that relative other fluid, reduced coefficient wear loss 9.4%-27.7% 7.6%-26.5%, respectively. display force temperature for 1.4%-13.2% 3.6%-11.2% lower than those When LB2000/multi-walled carbon nanotube (MWCNT) water-based was used external/internal ratio 2:1, showed best performance. This provides theoretical technical support selection
