“…Studies have shown that the energy generated by the interelectrode discharge can effectively heat, melt, and even gasify the material to be processed [21,22]. Through mechanism analysis [23] and parameter optimization [24], high strength-materials can be easily machined [25]. The interelectrode discharge in the gas medium can realize the loss of the tool electrode and form a certain density of metal deposit on the surface of the substrate material, which can be used for the additive manufacturing of the metal, which is a new type of processing [26].…”
