摘　　要：阐述了切削刀具用硬质涂层材料的研究现状,分别介绍了二元、三元以及三元以上的碳、氮基涂层材料,探讨了加入不同元素对刀具涂层的结构、机械性能、抗氧化性能和切削性能的影响。涂层材料逐渐由二元材料发展为多元材料,元素的添加使得涂层的结构发生改变,进而影响涂层的力学性能、抗氧化性能,综合性能得到提升,因此使涂层的切削性能得到提高。涂层刀具的应用显著提高了刀具的使用寿命,可有效减少资源的浪费,促进高速干切削技术的发展,刀具涂层技术的发展也促进了制造业向绿色制造发展。The research progress of cutting tool coating material is reviewed.The binary,ternary and multi-element carbon and nitrogen based coating materials are introduced respectively.The influence of different elements of cutting tool coating on its structure,mechanical properties,oxidation resistance and cutting performance is analyzed.It is indicated that the coatings material is developed from binary coatings to multi-component coatings.The cutting tool properties are improved along with more element addition,thus enhancing its mechanical property,oxidation resistance and cutting performance.The application of coated tools not only makes service life of cutting tools improved greatly and metal resources reduced,but also promotes the development of high-speed dry cutting technology for the cutting tool coating material and green manufacturing.
