    • PROBLEM TO BE SOLVED: To provide an electrode wire for electrical discharge machining increasing surface area of the electrode wire, increasing contact area with machining liquid at the time of electric discharge machining, and improving the machining speed by further increasing cooling speed. SOLUTION: This method relates to manufacturing of the electrode wire to be used in an electric discharge machine. A wire made of first metal containing copper and constituted of a first diameter is prepared. The wire is passed in a plating tank in which second metal having a vaporization temperature lower than that of the first metal is molten for fixed time and is cooled in the air. An alloy layer having higher hardness and a lower elongation percentage than those of the first metal and second metal is formed by a diffusion reaction of the first metal and second metal on the surface of the wire. On the alloy layer, a plating layer made of the second metal is formed. After being cooled in the air, the wire formed with the alloy layer and the plating layer is elongated to have a second diameter. Cracks are developed on the alloy layer and the plating layer by the high hardness and the low elongation percentage of the alloy layer to increase the surface area. COPYRIGHT: (C)2005,JPO&NCIPI
    • 要解决的问题:为了提供放电加工用电极线,增加电极线的表面积,在放电加工时增加与加工液的接触面积,并且通过进一步提高冷却速度来提高加工速度。 解决方案:该方法涉及在放电机中使用的电极线的制造。 制备由含有铜的第一金属制成并由第一直径构成的线。 电线通过电镀槽,其中汽化温度低于第一金属的第二金属熔融固定时间,并在空气中冷却。 通过第一金属和第二金属在导线表面上的扩散反应,形成具有比第一金属和第二金属高的硬度和低伸长率的合金层。 在合金层上形成由第二金属制成的镀层。 在空气中冷却后,由合金层和镀层形成的金属线被拉长以具有第二直径。 通过合金层的高硬度和低延伸率,在合金层和镀层上开发裂纹,增加表面积。 版权所有(C)2005,JPO&NCIPI
