【Abstract】 Under the different pressure(from 7.5 N/cm~2 to 30 N/cm~2) conditions, the electrical wear behaviors of CF-Cu-G composite have been studied. The results show: the friction coefficient is minimal when the pressure is equal to15 N/cm~2 and the friction coefficient increases with the increasing or decreasing of pressure. The wear loss ofcomposites varies with increasing pressure in the shape of u. Due to the forming of film, the contact drop ofcomposites slight increases at the beginning of electrical wear and then keeps steady.更多还原
