The novel composite material MoS₂-Al₂O₃ nanoparticles were synthesized via mussel-inspired chemistry of dopamine. Hot rolling lubrication performance of MoS₂-Al₂O₃ in water-based fluid was evaluated using a two-high rolling mill. Results showed that the synthesized MoS₂-Al₂O₃ nanofluid exhibited optimum hot rolling lubrication performance. The finish rolling thickness and rolled surface roughness reached lowest. Meanwhile the rolling force and oxide scale thickness of strips were respectively reduced by 26.9 % and 54.2 % compared with base-fluid lubricating condition. The ratio of Fe₂O₃ in oxide scale has lowered when rolled with nanofluids, owing to the antioxidation effect of nanoparticles during lubrication. MoS₂ has partially oxidized to MoO₃ and the excellent lubrication performance of MoS₂-Al₂O₃ nanofluid resulted from the lubricating film formed by these three nanoparticles.

新型复合材料MoS ₂ -Al ₂ O ₃纳米粒子是通过贻贝的多巴胺启发化学合成的。使用两辊高轧机评价MoS ₂ -Al ₂ O ₃在水基流体中的热轧润滑性能。结果表明，合成的MoS ₂ -Al ₂ O ₃纳米流体表现出最佳的热轧润滑性能。终轧厚度和轧制表面粗糙度达到最低。同时，与基础流体润滑条件相比，带钢的轧制力和氧化皮厚度分别降低了26.9％和54.2％。Fe ₂的比例当与纳米流体滚动时，由于纳米颗粒在润滑过程中的抗氧化作用，氧化皮中的O ₃降低了。MoS ₂已被部分氧化为MoO _3，并且由这三种纳米颗粒形成的润滑膜使MoS ₂ -Al ₂ O ₃纳米流体具有出色的润滑性能。
