HIGH-STRENGTH EROSION ELECTRODE |
摘要 |
<p>The invention concerns a high-strength erosion electrode having good electrical conductivity. The erosion electrode is made up of a steel core, an intermediate layer of copper or a copper-containing alloy, and an outer layer containing at least 40 % zinc. The steel core has a patented structure which contains between 0.6 and 1 wt. % carbon and occupies an area corresponding to between 50 and 75 % of the erosion electrode diameter, the intermediate layer occupying an area of between 5 and 40 % of the total diameter, the outer layer occupying an area of between 10 and 30 %, and the zinc content of the outer layer being between 40 and 60 wt. %.</p> |
