为研究MoS2植物油基纳米流体在镍基高温合金微量润滑钻削界面的摩擦学机理,以蓖麻油作为基础油,制备不同质量分数的纳米流体,搭建微量润滑钻削实验平台,以MoS2植物油基纳米流体作为润滑液,开展了干钻、蓖麻油微量润滑和纳米流体微量润滑条件下镍基高温合金GH4169的钻削加工试验,对比分析干钻、纯蓖麻油微量润滑和不同质量分数的MoS2纳米流体微量润滑对镍基合金钻削性能的影响.结果表明,MoS2纳米流体微量润滑降低切削温度100℃以上,减少后刀面磨损量达75％,提高表面质量和刀具使用寿命,这主要归功于纳米颗粒的导热性能,减少了刀屑粘结,同时纳米颗粒的修补作用能填补切削刃上的微小缺口,进一步延长刀具使用寿命.
Study on Influence of MoS2 Plant Oil-based Nanofluid on Drilling Performance of GH4169 Nickel-based Alloy
In order to investigate the tribological mechanism at the micro-lubricated drilling interface,plant oil-based MoS2 nanofluids were prepared using castor oil as the base oil with mass fractions of 1％,2％,and 3％.A micro-lubricated drilling experimental platform was established to conduct drilling experiments on nickel-based high-temperature alloy GH4169 under dry cutting,pure castor oil micro-lubrication,and different mass fraction MoS2 nanofluid micro-lubrication conditions.The influence of these lubrication methods on the drilling performance of nickel-based alloys was compared and analyzed.The results showed that MoS2 nanofluids can reduce average cutting temperatures by over 100 ℃,decrease tool wear by up to 75％,improve surface quality,and extend tool life by eight times.These improvements are mainly attributed to the thermal conductivity of nano-particles which reduces chip adhesion.Additionally,repair functions provided by nano-particles can fill in tiny gaps on cutting edges,further extending tool life.
