碳氮化钛基硬质合金金属陶瓷简介BRIEF INTRODUCTION OF CERMETS CUTTING TOOL TiCN基金属陶瓷具有良好的使用性能与WC基硬质合金相比它具有低密度、高硬度、对钢的摩擦系数小加工中显示出较高的红硬性、相近的强度、较低的腐蚀性和导热性切削时抗粘结磨损和抗扩散磨损在相同切削条件下TiCN基金属陶瓷刀具具有较高的寿命或在寿命相同的情况下可采用较高的切削速度被加工件有较好的光洁度。因此TiCN基金属陶瓷在许多加工场合下可成功取代WC基硬质合金填补了WC基硬质合金和陶瓷之间的空白特别适用于钢材的半精加工和精加工及耐磨耐蚀零件。TiCN substrate cermets cutting tool has very good application. Compared with tungsten carbide cutting tool cermets cutting tool has advantages of lower density harder much lower friction for machining steel better thermal stability when machining close toughness lower causticity and heat conduction better wear-resistance. Working in the same condition TiCN based cermets cutting tool has longer using life and can be used under faster cutting speed. We can get more finish work-piece with smoother surface using cermets cutting tool. From above we have used TiCN based cermets cutting tool to replace WC based carbide cutting tool in some fields successfully. It fills up the gap between WC based carbide and ceramic. It is suitable for semi-finishing and finishing machining of steel and wear part specially. TiCN基金属陶瓷采用精制高纯原料通过严格控制各个工艺环节而制备的具有优异特性的陶瓷制品具有高强度、高硬度、轻质抗腐蚀、抗氧化耐热性好等优异性能。广泛应用于高温、机械、电子、宇航、石油化工等诸多高科技领域。TiCN substrate cermets is used finished and pure material to produce cermets under control of each technol ogy tache strictly with good characters of high strength high hardness low causticity oxidation resistance and heat resistance etc. It is used widely in high-tech fields of high temperature engine electron space navigation petroleum and chemical industrial etc. 主要应用领域Main applications: 1. 金属陶瓷密封环1.
