Abstract Jet-Electrochemical machining (Jet-ECM) is a novel variation of traditional electrochemical in which electrically conductive material removed through anodic dissolution by means fine jet electrolyte. In this study, the effect nozzle geometry on removal characteristics are investigated physical experiments performed Jet-ECM system under development at university Manchester. A total 8 no...

--There are various techniques which can be used for the manufacture of microproducts, micro electromechanical systems (MEMS) based manufacturing .Broadly these techniques are photolithography, chemical etching, plating, laser fabrication. Micro machining may be seen as an ultra precision material removal process and by this process it is able to achieve micro form accuracy and nanometers finis...

It is shown that, in high-rate pulsed galvanostatic anodic dissolution of type CSN17335 and AISI 304 chromium–nickel steels electrolytes for electrochemical machining (ECM) (chloride, nitrate, mixed chloride–nitrate solutions with a conductivity 0.15 S/cm) using microsecond pulses duration 20–2000 ?s current densities the range 1–100 A/cm2, substantial fraction charge (up to ~40%) spent on form...

Aiming to solve the problems of low electrolyte flow rate at leading edge and trailing poor uniformity end clearance field during electrochemical machining (ECM) diffuser blades, a gap simulation model was established by designing three liquid-increasing channels cathode. The results indicate that hole channel (LIHC) with an outlet area S 1.5 mm2 distance L from center point 3.2 mm achieves opt...

Micro-hole fabrication at a high speed and accuracy of machining while maintaining surface quality is challenging. A core difficulty the removal products from extremely narrow gaps. To solve this problem, study proposes an approach that combines high-speed electrical discharge (EDM) with electrochemical (ECM) by using helical tube electrode matched internal external flushing. During drilling, m...

The strongly nonlinear switching kinetics of electrochemical metallization memory (ECM) cells are investigated using an advanced 1D simulation model. It is based on the electrochemical growth and dissolution of a Ag or Cu filament within a solid thin film and accounts for nucleation effects, charge transfer, and cation drift. The model predictions are consistent with experimental switching resu...
