摘    要:在改造过的MS-T3000摩擦磨损试验机上,以黄铜为摩擦副对热型连铸技术制备的铜银合金线材进行载流摩擦磨损试验,研究了电流对铜银合金导线载流摩擦磨损行为的影响.结果表明,电流强度对铜银合金干摩擦磨损行为有显著影响.电流在0~15 A范围内,随着电流的增加,摩擦系数与磨损率变化基本一致,呈现先减少后增加的趋势.电流较小时,接触电阻也比较小且较稳定;电流高时,接触电阻比较大,波动剧烈,而且有电弧出现.铜银合金导线在带电条件下的主要磨损形式为磨粒磨损、粘着磨损以及以电化学作用为主的氧化磨损或腐蚀磨损.

Abstract:The friction and wear behavior of Cu-Ag alloy conducting wire against brass block was investigated.Wear tests were conducted under laboratory conditions with a sliding friction and wear apparatus that simulated train motion under electrical current conditions.The results indicated that the electrical current intensity has a notable effect on the friction and wear behavior of Cu-Ag alloy conducting wire.Within the studied range of electrical current,with electrical current increasing,friction coefficient and...
Keywords:Cu-Ag alloy conducting wire  friction and wear  electrical current  performance
