摘要
以单晶硅作电极,用电火花成形机在煤油介质中对45钢进行表面强化实验研究。分析了脉冲宽度、脉冲间隔、峰值电流、加工时间对强化层厚度的影响,并对强化层的显微硬度和耐磨性进行了分析。研究结果表明,合适的工艺参数和加工时间,能使工件的表面获得具有一定的厚度、较高硬度和耐磨性的强化层。
In the paper, experiments of surface strengthening process were macle with single crystal silicon as electrode material and 45 steel as substrate material in kerosene on EDM forming machine. The effects of pulse width, pulse interval, peak current and process time on intensified layer are analyzed. And the micro-hardness and the property of strengthening layer are also analyzed. The resuits show that a certainty thickness＇ intensified layer and satisfying surface quality with high microhardness and good wear-resistance can be obtained by proper process time and processing parameters.
