EDMECMHigh entropy alloyThe thermal, mechanical and chemical stability of a material can theoretically be estimated by the Gibbs free energy of formation. Based on this, a new class of alloys - High Entropy Alloys (HEAs) - was designed in the past two decades, maximizing the entropy for a ...
Therefore, electrical discharge machining (EDM) as well as electrochemical machining (ECM) are investigated as alternatives. This includes the fundamental analysis of surface morphology as well as resulting subsurface properties for two state-of-the-art second generation HEAs....
To solve this problem, this study proposes an approach that combines high-speed electrical discharge machining (EDM) with electrochemical machining (ECM) by using a helical tube electrode with matched internal and external flushing. During high-speed electrical discharge drilling, matching the internal ...
With the change in gap distance and the depth of the hole drilled, the dominant machining mechanism is graduated changed from EDM to electrochemical discharge machining (ECDM) and ECM. The formation mechanism of the recast layer on nickel alloy was investigated by comparing the surface characters ...
