摘　　要：纳米生物润滑剂作为替代矿物型润滑介质的绿色微量润滑剂,已成为学术界与工业界的研究与关注焦点。然而,纳米生物润滑剂微量润滑加工物理学作用机制尚不清楚,难以为其工业化应用提供精准指导与选用原则。为解决上述需求与技术问题,综述了纳米生物润滑剂组分及物理特性,揭示了纳米增强相、基础流体、添加剂对加工性能的影响规律,阐述了纳米增强相在纳米生物润滑剂中的动力学行为与分散机制。其次,揭示了多能场雾化机制、切/磨削区流场分布及微液滴浸润动力学行为,发明了微量润滑新型供给与雾化装置。进一步地,分析了切/磨削加工材料去除热物理机制,研究了先进的多场赋能热损伤抑制策略,构建了纳米生物润滑剂微量润滑加工技术体系。结果表明,纳米生物润滑剂在热源抑制与热耗散特性调控方面效果显著,多场赋能纳米生物润滑剂微量润滑可作为浇注式加工的替代工艺,采用断续有序的凹槽织构砂轮辅助质量分数为2.5%的MWCNTs-棕榈油纳米生物润滑剂微量润滑磨削单晶镍基高温合金DD5,与传统的浇注式磨削工艺相比,磨削力可降低12%,磨削温度可降低9%,表面粗糙度值可降低6%。展望了纳米生物润滑剂发展路线图,为工业界与学术界提供技术支持与理论指导。As a green minimum quantity lubrication lubricant replacing mineral oil,nano-biolubricants have become the focus in academic and industrial circles.However,the physical mechanism of minimum quantity lubrication machining is still unclear,which makes it difficult to provide precise guidance and selection principles for industrial application.To address the aforementioned needs and technical issues,the components and physical properties of nano-biolubricants are reviewed.The influences of nano reinforcement phase,basic fluid,and additives on machining performance are revealed,and the dynamic behavior and dispersion mechanism of nano reinforcement phase in nano-biolubricants are elucidated.Secondly,the multi energy field atomization mechanism,flow field distribution in the cutting/grinding zone,and dynamic behavior of micro droplet infiltration are revealed,and a new type of minimum quantity lubrication supply and atomization devices are invented.Furthermore,the thermal physical mechanism of material removal in cutting/grinding processing is analyzed.Advanced multi field energized thermal damage suppression strategies are studied,and a minimum quantity lubrication machining system for nano-biolubricants is constructed.The results indicate that nano-biolubricants have significant effects in controlling heat source suppression and thermal dissipation characteristics,and multi field energized nano-biolubricants minimum quantity lubrication can be used as an alternative process for flooding machining.Compared with traditional flooding grinding technology,using intermittent groove textured grinding wheel to assist in minimum quantity lubrication grinding of single crystal nickel based superalloy DD5 with MWCNTs palm oil nano-biolubricants with a mass fraction of 2.5%can reduce the grinding force by 12%,the grinding temperature by 9%,and the surface roughness value by 6%.The development roadmap of nano-biolubricants is expected to provide technical support and theoretical guidance for the industrial and academic communiti
