WC和Mo_2C添加对Ti（C,N）基金属陶瓷切削性能的影响
Research on Cutting Performance of Ti（C,N）-based Cermets with WC and Mo_2C Addition
摘要
Abstract
Mo2C has been used in conventional Ti（C,N）-based cermets to improve its wettability between hard phase and binder phase.Recently,some researchers have attempted to develop Ti（C,N）-based cermets free of Mo.To investigate the effect of replacing Mo2C by WC in conventional Ti（C,N）-based cermets,the cutting performance of cermets with the addition of WC and Mo2C was studied,respectively.Wear morphology of cutting tool was observed by SEM,and element distribution of tool surface was analyzed by EDS.The results showed that the cutting tool life of cermets with WC addition was equal to that with Mo2C addition.When the size of the initial WC powder decreased,the cutting tool life could be prolonged,the zonal tangle chip changed to helix chip,and the chip build-up could be reduced.Diffusion wear,oxidation wear accompanied by abrasive wear were considered to be the main wear mechanisms of the cermets.关键词
