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.
