摘要
以碳碳复合材料和铬青铜作为配副,研究了受流条件下碳碳复合材料的摩擦学特性。结果表明:速度、载荷和电流是影响受流条件下碳碳复合材料摩擦学特性的重要因素。在电流一定的条件下,碳碳复合材料的摩擦因数和磨损率随速度的增大而增大;摩擦因数随载荷的增加而增大,而磨损率随载荷的增加而减小。在载荷一定条件下,随着电流的增加,碳碳复合材料的摩擦因数减小而磨损率增大。与一般条件下的摩擦学特性相比较,碳碳复合材料在受流条件下的摩擦因数明显降低,而磨损率却明显提高。
Using C/C composite and chrome bronze as a couple,the tribological characteristic of C/C composite was studied under the condition of current-receiving.The result shows that speed,load and current are important factors to influence the tribological characteristic of C/C composite.The friction coefficient and wear rate increases with the increase of speed at fixed current.The friction coefficient increases but the wear rate decreases with the increase of load.The friction coefficient decreases but the wear r...
