研究了电流强度的变化（４Ａ／ｃｍ~２－１６Ａ／ｃｍ~２）对碳纤维－铜－石墨复合电刷材料电磨损性能的影响，并与纯机械磨损进行了对比；用扫描电镜对复合材料磨面进行了观察分析，探讨了电磨损机理。
The effect of current density (4A / cm ~ 2-16A / cm ~ 2) on the electrical wear properties of carbon fiber-copper-graphite composite brush was studied and compared with pure mechanical wear. The grinding surface was observed and analyzed, and the mechanism of electric wear was discussed.
