摘　　要：利用涂层硬质合金刀具对Inconel 718进行了高速干切削试验,采用扫描电子显微镜SEM和能量分散光谱EDS扫描,对不同切削参数下刀具的损坏形态和损坏机理进行了研究。分析结果表明刀具损坏形式主要有前刀面磨损、后刀面磨损、剥落和崩刃。刀具损坏机理主要是粘结磨损、磨粒磨损、氧化磨损和扩散磨损等。The dry - cutting tests of high speed turning Inconel 718 using coated carbide tool is presented. The worn surface morphology of tool and its abrasion mechanism are studied by scanning electronic microscope （SEM） and energy disperse spectrum （EDS）. The results show that the failure modes are rake wear, flake wear,flaking and chipping and the main failure mechanisms of tool are adhesive wear, abrasion wear, oxidation wear, diffusive wear and so on.
