| 摘 要： | 在高频淬火态GCr15轴承钢切削过程中施加高能脉冲电流,研究了高能电脉冲对淬火态GCr15钢切削性能的影响。结果表明,在脉冲电流的作用下,主切削力、轴向表面粗糙度、表面硬度以及刀具磨损状况都显著降低。对高频淬火态GCr15轴承钢而言,脉冲电流的电致塑性效应与焦耳热效应能够促进位错运动,从而在较低温度与较短时间内达到回火效果,提高材料表面塑性变形能力,有效改善其切削加工性能。

| Abstract: | Electropulsing was introduced into the cutting process of the high-frequency quenched GCr15 bearing steel. Experiment results indicate that the main cutting force, axial roughness on machined surface, surface microhardness and tool wear show a significant decreasing tendency under the effect of electropulsing. For high-frequency quenched GCr15 bearing steel, the electroplasticity effect and Joule heating effect can accelerate the movement of dislocations, then the material tempered in a lower temperature and shorter time, the plastic deformation ability and the cutting properties of GCr15 bearing steel have a remarkable improvement. |
