| Abstract: | Under no current or the different current intensity (from 4A/cm2 -16A/cm2) conditions, the electrical wear behaviors of CF-Cu-G composite increases with the increase of current intensity. The electrical wear volume loss of the composite increased by 2-7 times compared with no current. The carbon fiber of composites improves electrical wear behaviors of the brush and decreases wear volume loss of the brush. |
