摘　　要：刀具磨损严重、服役寿命短仍然是切削加工所面临的难题。随着现代制造业的发展,钛合金、高温合金等难加工材料在工业中广泛运用。但由于这些材料具有低导热系数、变形系数小等特点,在机械加工中存在切削力和切削温度高、刀具磨损严重等问题,严重缩短了刀具的服役寿命。通过表面织构技术和表面涂层技术在刀具切削表面置入微纳织构和涂层可以显著改善切削性能;特别是在减小刀具磨损、降低切削力、切削温度以及刀-屑接触界面摩擦因数等方面具有显著效果。系统概述微纳织构涂层刀具的作用机理、切削性能以及应用领域,对微纳织构涂层刀具后续发展有重要推动意义。首先,介绍微纳织构涂层刀具的制备方式。其次,分析总结微纳织构涂层刀具的作用机理,并从抗磨损性、抗粘结性和刀具寿命三个方面总结微纳织构涂层刀具的自身性能。随后,从切削力、切削温度、刀-屑接触处的摩擦因数三个方面总结微纳织构涂层刀具的切削性能。最后对微纳织构涂层刀具在现代制造业中的应用进行阐述。提出在刀具切削表面同时置入微纳织构和涂层的当前研究现状以及未来发展方向,可为进一步研究微纳织构涂层刀具在切削加工中改善切削性能以及加工表面质量与性能提供参考。Tool wear is a serious problem,and a short service life is a challenge in cutting-processing.Following the development of the modern manufacturing industry,titanium alloys,high-temperature alloys,and other difficult-to-machine materials have been adopted widely.However,these materials exhibit low thermal conductivity and small deformation coefficients among other characteristics,resulting in a high cutting force and cutting temperature,tool wear,and serious problems in cutting,thus considerably shortening the service life of the tool and affecting the machining surface quality.Following the advancement of science and technology,green cutting technology is widely used in the modern manufacturing industry,thereby increasing demand in the cutting tools field.Therefore,the use of cutting fluid in the cutting process,which not only improves the lubrication effect of the cutting process,but also reduces tool wear and improves the machining surface quality and performance has been considered.However,the large amount of cutting waste fluids causes environmental pollution and has a serious impact on the operator's health.Therefore,to better respond to green manufacturing and achieve sustainable development,surface coating technology is applied to tool surface coatings with high hardness,high abrasion resistance,and other properties of hard coating materials and solid lubricating materials with a low coefficient of friction(soft coatings).These act as a chemical and thermal barrier to avoid direct contact between the tool and workpiece,reducing the friction and interaction between the tool and workpiece to enhance the tool's oxidation resistance,anti-adhesion properties,and resistance to abrasive wear,thereby extending the tool life and improving the cutting tool performance.In addition,through the principle of friction biomimicry,surface texturing technology is used to place micro-textures on the rake or flank face of the tool,similar to the surface texture of certain natural living creatures,which can improve the frictio
