摘要: Electrochemical machining (ECM) is a complex technology used to shape conductive materials, for example hard metals. The workpiece material removed by anodic dissolution in aqueous electrolytes at extremely large current densities. Hard metals are non-homogeneous and consist of particles, e.g. carbides, embedded softer matrix formed such as cobalt, nickel, iron or alloys. final determined custom made tool, the cathode, new technique with confined electrolyte jet (Jet-ECM). An optimisation this process intents ascertain detailed information about influence potential distribution, composition electrolyte, flow geometry, electrochemical behaviour mechanism components structure interface material/electrolyte. Experiments on WC6Co, common metal consisting WC particles Co binder, presented an example.
