摘要:

研究了水基和油基纳米流体静电雾化润滑及不同外/内流量比的纳米流体同轴静电雾化润滑的荷电与雾化特性及润湿性能,对比分析了这些条件下的铝合金铣削性能,并结合熵权-逼近理想解排序法对铣削性能进行了综合评价。结果表明,纳米流体同轴静电雾化润滑的铣削性能均优于纳米流体静电雾化润滑,其中外/内流量比为2∶1的纳米流体同轴静电雾化润滑表现出最佳的铣削性能。这归因于其优异的荷电性能与雾化效果、良好的润湿性能及该外/内流量比下纳米流体复合雾滴优异的冷却润滑能力。相比于纳米流体静电雾化润滑和其他外/内流量比的纳米流体同轴静电雾化润滑,外/内流量比为2∶1的纳米流体同轴静电雾化润滑的铣削力和刀具磨损分别减小了3.52%~12.47%和18.33%~57.41%。

Abstract:

The charge and atomization performance as well as wetting property of water-based and oil-based nanofluid electrostatic atomization lubrication and nanofluid coaxial electrostatic atomization lubrication with different external-internal flow ratios were studied herein. The milling performance of aluminum alloy under these conditions was compared and analyzed, and the milling performance was comprehensively evaluated by the entropy weight-TOPSIS method. The results show that the milling performance of nanofluid coaxial electrostatic atomization lubrication is better than that of nanofluid electrostatic atomization lubrication. The nanofluid coaxial electrostatic atomization lubrication with an external-internal flow ratio of 2∶1 shows the best milling performance. This is attributed to its superior charge performance, atomization effect, and excellent wetting property, as well as the outstanding cooling and lubrication capabilities of nanofluid composite droplets under this external-to-internal flow ratio. Compared with nanofluid electrostatic atomization lubrication and nanofluid coaxial electrostatic atomization lubrication with other external-internal flow ratios, the milling force and tool wear decreased by 3.52%-12.47% and 18.33%-57.41%, respectively, under the 2∶1 external-to-internal flow ratio of nanofluid coaxial electrostatic atomization lubrication.

Key words: nanofluid, electrostatic atomization lubrication, coaxial electrostatic atomization lubrication, charge performance, wetting property, aluminum alloy milling, entropy weight-technique for order preference by similarity to ideal solution (TOPSIS)
