电阻焊电极用 WC/Cu(Cu-Cr)复合材料的开发及应用研究

A Study on Manufacture and Application of the WC/Cu(CuCr) Composite Materials Used for Resistance Welding Electrode

用粉末冶金冷等静压→烧结→热挤压方法制备的ＷＣ／Ｃｕ（ＣｕＣｒ）复合材料，具有均匀的组织和优良的高温性能。用作电阻焊电极变形小，不粘焊，使用寿命超过常用ＣｕＣｒＺｒ合金电极，且修复再生能力强。

In this paper,WC/Cu(CuCr) composite material were manufactured by the method of powder metallurgy cold isostatic pressingsinteringheat extrusionThe materials possesed uniform microstructure and better propertiesThe number of points in continuoas welding of composite resistance welding electrades are higher than CuCrZr alloy which is used widely today
