摘要： A gamma phase brass coated EDM wire electrode is processed to produce distinct particulate of the brittle gamma phase alloy where these particulate have a uniquely describable distribution of geometric parameters. The distribution of particles determined by analyzing random cross sections of the wire electrode using standard optical metallographic procedures contains a minimum number of particles with a minor axis of less than 1.5 μm and a higher proportion of larger aspect ratio (quotient of the values of major axis and minor axis] particles. Such wire electrodes are found to contain less loose debris than electrodes described in the prior art, i.e. are cleaner than prior art gamma wires without suffering any degradation in cutting speed performance.

摘要： An EDM wire having an outer coating of gamma phase brass with an overlayer of continuous unalloyed zinc or ductile epsilon phase brass entrapping the gamma phase and a process for manufacturing the EDM wire is provided. A second process for synthesizing a ductile epsilon phase brass coating on the aforementioned and other substrates is also provided. The first process includes coating a copper bearing metallic core with zinc. The zinc coating is then converted to gamma phase brass via a diffusion anneal and subsequently re-coated with zinc prior to being cold drawn to its finish diameter.

The zinc coating is then converted to gamma phase brass via a diffusion anneal and subsequently re-coated with zinc prior to being cold drawn to its finish diameter. The process of converting a zinc coating to a ductile epsilon phase brass includes heat treating the wire at a temperature low enough to minimize or eliminate changes in the mechanical properties of the composite wire.

摘要： An EDM wire having an outer coating of epsilon phase brass and a process for manufacturing the EDM wire is provided. The process includes coating a copper bearing metallic core with zinc. The zinc coating is then converted to epsilon phase brass by heat treating the wire at a temperature low enough to minimize or eliminate any resulting changes in the mechanical properties of the wire. The coated core wire may be drawn to a finish size prior to heat treatment which will result in a wire with a substantially continuous epsilon phase coating.
摘要翻译：提供了具有ε相黄铜的外涂层的EDM线和用于制造EDM线的方法。该方法包括用锌涂覆铜轴承金属芯。然后通过在足够低的温度下对线材进行热处理将锌涂层转化为ε相黄铜，以最小化或消除导线的机械性能的任何变化。涂覆的芯线可以在热处理之前被拉伸至精加工尺寸，这将导致具有基本上连续的ε相涂层的导线。
