采用辉光离子氮化新工艺强化金属表面,是提高工件表面耐磨性和抗蚀能力的有效方法。在实际生产中常常会遇到一些较长的工件,超出氮化炉的有效高度或遇到一些较长的内孔要求氮化的工件,如果采用常规处理方法就不易达到表面强化的目的。我厂生产的XB—10型和SE—90型两种注塑机上的揽龙和揽龙筒就属于即较长又要求内孔氮化的部件。该部件在200℃左右的温度下承受挤压塑料的摩擦作用。对于这种部件,要求它必须具有耐温、耐压、耐塑
Glow ion nitriding new technology to strengthen the metal surface is to improve the surface wear resistance and corrosion resistance of the effective method. In actual production often encounter some of the longer workpieces, beyond the effective height of the nitriding furnace or meet some of the longer bore requirements of the nitride workpiece, if the use of conventional treatment methods is not easy to achieve the purpose of surface hardening. I plant production XB-10 and SE-90-type injection molding machine on both the dragon and dragon tube belonging to the longer that the inner hole nitriding components. The parts withstand the friction of extruded plastic at temperatures around 200 ° C. For such components, it must be temperature, pressure, plastic
