采用强流脉冲电子束对 YW2硬质合金刀具进行辐照表面改性。根据Box-Behnken中心组合方法设计3因素3水平实验方案,以刀具表面的显微硬度和粗糙度为响应值,对加速电压、工作电流和脉冲次数等辐照工艺参数进行优化。实验结果表明,经综合分析优化后的脉冲电子束辐照最优参数：加速电压10 kV,工作电流180 A,脉冲次数45次。与未经处理刀具相比,该工艺下辐照后的 YW2硬质合金刀具的显微硬度明显提高,而粗糙度值降低；对 TC4钛合金的切削实验结果也验证了优化工艺处理后刀具的切削性能明显得到提高。
The YW2 cemented carbide tools were surface modified by high current pulsed electron beam irradia-tion.An experiment program with three factors and three levels was designed by using central composite meth-od of Box-Behnken.The effects of accelerate voltage,current,pulse number on the microhardness and rough-ness of YW2 carbide tools were optimized with response surface methodology.The results show that the opti-mal parameters are following:accelerate voltage of 10 kV,current of 180 A and pulse number of 45 times. Compared with the untreated tool,the irradiated YW2 tool under optimal condition has higher microharness and lower roughness.The cutting performance of the irradiated YW2 tool under optimal condition has improved through the cutting tests of titanium alloy.
