Diamond tools are known to wear rapidly during the machining of ferrous materials because of the catalytic effect of iron on diamond graphitization. This work aims to perform a relative comparison of the wear mitigation efficacy of candidate two-dimensional (2D) materials, viz., graphene oxide (GO), hexagonal boron nitride (hBN), molybdenum disulfide (MoS₂) and tungsten disulfide (WS₂), when used as cutting fluid additives during diamond turning of steel. The 2D material suspensions (0.15 wt.%) are first characterized for their hydrodynamic diameter distributions. Multi-pass turning studies are then conducted using monocrystalline diamond tools. Tool wear, cutting forces and surface roughness are used as the comparison metrics. Overall, graphene oxide has the highest reduction in tool wear (60 %) over the baseline case. It is followed by hexagonal boron nitride, tungsten disulfide and molybdenum disulfide that offered 52 %, 45 % and 38 % wear reduction, respectively, over the baseline case. Overall, hBN provides the best combination of low tool wear, low cutting forces and low surface roughness. The tool wear mitigation efficacy of the materials can be explained in terms of their specific chemical/physical interactions at the iron-diamond interface. X-ray Photo Spectroscopy (XPS) measurements reveal a clear correlation between the tool wear trends and strength of the graphitic carbon/carbide signals obtained on the machined surfaces. XPS measurements in the B1s and S2p regions shed light on the chemical reactions responsible for the performance of hBN, WS₂ and MoS₂. The unique surface chemistries of the resulting surfaces offer the potential of a rich exploration landscape for downstream applications.

众所周知，由于铁对金刚石石墨化的催化作用，金刚石工具在铁类材料的加工过程中会迅速磨损。这项工作旨在对候选二维（2D）材料（即氧化石墨烯（GO），六方氮化硼（hBN），二硫化钼（MoS ₂）和二硫化钨（WS））的减缓磨损效果进行相对比较。_2个），用作钢的金刚石车削时的切削液添加剂。首先对2D材料悬浮液（0.15 wt。％）的流体动力学直径分布进行表征。然后使用单晶金刚石工具进行多道次车削研究。刀具磨损，切削力和表面粗糙度用作比较指标。总体而言，氧化石墨烯在工具磨损方面的降低幅度最大（60％）。其次是六方氮化硼，二硫化钨和二硫化钼，在基准情况下分别减少了52％，45％和38％的磨损。总体而言，hBN提供了低刀具磨损，低切削力和低表面粗糙度的最佳组合。可以通过在铁-金刚石界面处的特定化学/物理相互作用来解释材料的工具磨损缓解功效。X射线光谱（XPS）测量表明，刀具磨损趋势与在加工表面上获得的石墨碳/硬质合金信号强度之间存在明显的相关性。B1s和S2p区域的XPS测量揭示了负责hBN，WS性能的化学反应₂和MoS ₂。所得表面的独特表面化学性质为下游应用提供了丰富的勘探前景。
