摘要

为了提高电接触材料的导电、导热等性能

笔者采用粉末冶金溶渗技术制备出WC/Cu滑动电接触材料

并对其显微组织和性能进行了系统研究。结果表明:WC60～90/Cu滑动电接触材料随着WC含量的增加

材料的密度由11.508 g/cm3增加到13.305 g/cm3

硬度由HB187增加到HB477

导电率由14.6 m/（Ω.mm2）下降到10.6 m/（Ω.mm2）。耐磨性随着WC含量的增加显著提高

但高Cu含量的孕育期较长。磨损机制以磨粒磨损和表面接触疲劳为主。建议使用含量为WC70/Cu30～WC80/Cu20的滑动电接触材料。

Abstract

WC/Cu slip electrical contact materials were fabricated with powder metallurgy to improve the properties of electrical contact materials such as electric and thermal conductivity.The microstructure and the properties of the WC/Cu composite materials were tested.The results show that with WC content increasing

the density of the WC60～90/Cu composites rises from 11.508 g/cm3 to 13.305 g/cm3

hardness from HB187 to HB477

and conductive rate drops from 14.6 m/（Ω·mm2） to 10.6 m/（Ω·mm2）.Moreover

the resistance to wear is remarkably enhanced.The abrasive wear and fatigue-based surface contact is the main abrasive mechanism

and the WC70/Cu30～WC80/Cu20 is suggseted.
