摘　　要：复合黏结相硬质合金刀具由于具备较好的综合力学性能,在难加工材料加工领域具有较好的应用前景。采用放电等离子烧结技术制备了高性能Co-Mo-Ni复合黏结相WC基硬质合金车刀片,通过干式车削TC4钛合金单因素实验,分析了切削速度、进给量和背吃刀量对刀具寿命、磨损过程以及失效机理的影响过程。实验结果表明,所制备的刀具材料具有较高的切削适应性,通过进一步刀具结构设计有较好的应用前景。Cemented carbide tools containing composite binder phases have extensive application prospects for cutting difficult-to-machine materials due to their good comprehensive mechanical properties.In this study,high-performance WCbased cemented carbide lathe tools containing Co-Mo-Ni composite binder phase are prepared by spark plasma sintering.The effects of cutting speed,feed rate and cutting depth on the tool life,wear mechanism and failure mode in dry turning TC4 titanium alloy are analyzed by single factor experiment.The results show that prepared tool materials have high cutting adaptability,and have good potential applications by further designing the tool structure.
