摘　　要：碳化钨插件是核主泵电机推力轴承中重要的安全部件,对推力瓦作轴向与径向限位。碳化钨插件工作在强放射性的高压水中,具有耐高压、耐辐照、耐磨损和耐腐蚀的特点。在对其进行线切割后,新增磨削工序,以消除表面微裂纹,通过该工艺改进,解决了部分插件冲击强度不达标的问题。The tungsten carbide plugin,as the important safe part used in bearings of nuclear main pump motors,implements the axial and radial limit against the thrust pads.The tungsten carbide plugin works in the radioactive high-pressure water,possessing features of anti-high-pressure,anti-irradiation,anti-wearing and anti-corrosion.The technological process is improved,adding a grinding process immediately after wire cutting to eliminate the micro cracks on the surface,thus.the problem that the shock strength of pars of plugins is not to standard.
