Abstract

Abstract: In view of the problems that cutting fluids were not easy to penetrate into the cutting areas for lubrication, it was proposed to prepare nanofluids using multi-walled carbon nanotube(MWCNTs) composites filled with OA as additives. The nanofluids were easier to penetrate into the cutting areas, and the composites might release OA during cutting processes to enhance lubrication. The thermophysical properties of the nanofluids were tested, and the performance of the nanofluids in cutting GCr15 steels under minimal quantity lubrication(MQL) conditions was evaluated. The cooling and lubrication mechanism of the composites in the cutting processes was analyzed. The results show that nanofluids prepared by the composites are significantly improved in terms of dispersion stability, heat transfer and wettability. Compared with ordinary emulsion, the cutting force, cutting temperature and surface roughness are reduced by 15%, 25%, 16%, respectively, and the and tool life is enhanced by 22% when turning with composite nanofluids.

Key words: multi-walled carbon nanotube(MWCNT), oleic acid(OA) composite, nanofluid, cutting performance

摘要： 针对切削液不易渗入到切削区起润滑作用的问题，提出利用内部填充油酸（OA）的多壁碳纳米管（MWCNTs）复合物为添加剂制备纳米流体，该纳米流体更易渗入到切削区，且复合物可在切削时释放油酸起增强润滑的作用。首先测试了纳米流体的热物理性能，考察了它在微量润滑（MQL）条件下车削GCr15钢的性能，然后研究了切削过程中复合物的冷却润滑特性。结果表明：与普通MWCNTs相比，复合物能更好地提高纳米流体的分散稳定性、传热性和润湿性；与普通乳化液相比，复合物纳米流体车削时的切削力减小约15%，切削温度降低约25%，工件表面粗糙度值减小16%，刀具耐用度提高了22%。
