Abstract

The influence of the pulse energy on the performance of copper electrodes with added graphite in the electrospark piercing of tool steel is studied. With increase in the pulse current, the electrode wear increases, if the other parameters are unchanged. In absolute terms, the wear is less in the presence of thermally expanded graphite and greater in the presence of colloidal graphite.

电火花加工中铜-石墨复合电极的相对磨损

摘要

研究了脉冲能量对工具钢电火花穿孔中添加石墨铜电极性能的影响。在其他参数不变的情况下，随着脉冲电流的增加，电极磨损增加。就绝对值而言，存在热膨胀石墨时磨损较小，存在胶体石墨时磨损较大。
