摘要：

In this paper, the effects of graphite content on the contact voltage drop of CNTs-Ag-G composites fabricated by means of powder metallurgy are studied. The results show that the contact voltage of the composite brushes as function of the percentage composition of graphite can be characterized by a parabola curve. The contact voltage drop of composite brushes first ascends then tends to stabile with wear time; and the negative brush is always bigger than the positive brush.
