Abstract

Electrochemical jet machining (EJM) on concave surfaces or cavities is challenging because the jet and film flow fail to form. This work presents an in-situ electrolytic gas and plasma assistance approach to enable EJM under electrolyte. A structured nozzle cathode induces pressurized and insulating gas around electrolyte at the gap, generating a constrained jet and film flow. This serves to allow a precise and effective submerged EJM (SEJM) routine. Compared to EJM in air, SEJM shows more concentrated current distribution owing to a thinner film flow by the gas assistance, leading to a 65 % improvement in surface finish and a 16 % reduction of machining overcut.

利用原位气体辅助进行浸没式电化学喷射加工

在凹面或空腔上进行电化学射流加工（EJM）具有挑战性，因为射流和薄膜流无法形成。这项工作提出了一种原位电解气体和等离子体辅助方法，以实现电解液下的电化学喷射加工。结构化喷嘴阴极可在间隙处的电解质周围诱导加压和绝缘气体，从而产生受限的射流和薄膜流。这有助于实现精确有效的浸没式电积电解法（SEJM）。与在空气中进行的 EJM 相比，SEJM 由于气体辅助产生的薄膜流更薄，因此电流分布更集中，从而使表面光洁度提高了 65%，加工过切减少了 16%。
