摘　　要：涂层硬质合金刀具具有良好的抗机械和抗热载荷冲击性能,以及较低的摩擦因数,在常温及高温下耐磨损性能优异,广泛应用于难加工材料的精密、半精密加工。对涂层硬质合金刀具进行表面处理后,刀具表面残余应力会发生演变,并会对刀具磨损产生影响。介绍了针对以上问题的国内外研究现状,并对高性能涂层硬质合金刀具的未来发展进行了展望。The coated carbide tool has good capability to resist mechanical impact and thermal load impact,and has low friction factor.With excellent wear resistance at room temperature and high temperature,the coated carbide tool is widely used in precision and semi-precision machining of the difficult-to-machine materials.After surface treatment of the coated carbide tool,the residual stress on the tool surface will evolve and affect the tool wear.The research status at home and abroad for the above issues were introduced,and the future development of the high-performance coated carbide tool was prospected.
