解釋
碳塗層光纖-
We also studied the dynamic characteristics of cf / cu ( c ) - cu composites, the results show that, by the method of graphite is coated with copper, the coefficient of friction and the wear rates remarkably decreased. with the increase of the copper coated carbon fiber content, the wear rates of cf / cu ( c ) - cu composites is notably decreased, while the coefficient of friction is increased. with the increase of electric current density, the wear rate of cf / cu ( c ) - cu composites is increased
研究發現，碳纖維鍍銅石墨-銅復合材料的電摩擦磨損性能與碳纖維含量存在一最佳值，當碳纖維含量為0 . 6時，其電摩擦磨損性能最好；對于不同電流密度下的電磨損性能的比較可以發現，通電磨損時的電摩擦系數要小於機械磨損時的摩擦系數，碳纖維鍍銅石墨-銅復合材料的電摩擦系數隨電流密度增大先減小而後增大，在電流密度為15a cm ~ 2時達到最小值；通電磨損量要遠大於機械磨損量，且隨著電流密度增大，磨損量增加。 -
