掺钴镁新型线切割钼丝的制备

Manufacture of the New WEDM Molybdenum Wire Doped Cobalt and Magnesium

介绍了一种掺钴镁新型线切割钼丝的制备方法。在二氧化钼粉中加入钴、镁元素,经粉末冶金和机械加工制作出用于电火花线切割加工的钼合金电极丝。不仅改善了线切割用钼丝的高温性能、抗拉强度、放电效率和抗损性能,而且提高了其应用价值。

The manufacture method of a new wire electrical-discharge machining（WEDM）molybdenum wire doped cobalt and magnesium are introduced. The cobalt element and magnesium element added into molybdenum dioxide powder,then process with powder metallurgy and machining.This research improves high temperature performance,tensile strength,discharge efficiency and damage resistance of WEDM molybdenum wire,also improves the applying value.
