摘　　要：采用金相显微镜、扫描电镜、能谱仪等分析手段,分别对四种车削加工油井管螺纹的涂层硬质合金螺纹梳刀的磨损机理及使用寿命进行了研究。结果表明:刀具显微组织均匀细小时,主要失效形式为磨损失效;大块状的切屑黏结、涂层剥落、裂纹等现象表明,刀具的主要磨损机理为黏结磨损、磨粒磨损、涂层剥落、微崩刃。The wear mechanism and service life of four kinds of OCTG thread tools are studied by using the metallographic microscope,SEM,EDS.The results show that when the microstructure of the tool is uniform and fine,the main failure mode is wear failure;the phenomenon of large chip bonding,coating peeling,cracks and so on shows that the main wear mechanism of the tool is bond wear,abrasive wear,coating peeling,micro chipping.
