摘    要:在先进的多功能摩擦磨损试验机上,对碳刷/铜环在有、无电流条件下的滑动摩擦学行为进行研究,并对电弧行为进行分析。结果表明:法向载荷是载流摩擦过程中电弧产生的主要控制因素之一;电弧强度随法向载荷的降低而增强,随电流的增大而增强;摩擦过程的不稳定和摩擦系数的波动强烈地依赖于电弧;碳刷的磨损量和磨损机制受电弧影响显著;当没有电弧产生时,在有、无电流条件下碳刷的磨损量没有显著差别,此时,碳刷磨损机理主要是机械磨损;当有电弧产生时,载流条件下碳刷的磨损量远高于无电流实验的,并随着电流的增大和法向载荷的降低而迅速增大,磨损机理主要是电弧烧蚀和粘着磨损,并伴有一定的材料转移。

关 键 词:摩擦  磨损  电流  电弧  碳/铜

Abstract:The tribological behaviors of carbon block sliding against copper ring with and without electric current applied were investigated by using an advanced multifunctional friction and wear tester, and the electric-arc behaviors were analyzed in detail. The results show that the normal load is one of the main controlling factors for generation of electric arc during friction process with electric current applied. The strength of electric arc is enhanced with the decrease of normal loads and the increase of elec...
Keywords:friction  wear  electric current  electric arc  carbon/copper
