Electrochemical polishing method for flexible braided electrodes and complex internal channels

Abstract

A flexible braided electrode and a method for electrochemical polishing of complex internal channels, belonging to the field of electrolytic processing, wherein the flexible braided electrode is formed by braiding a plurality of flexible conductive wires and a plurality of flexible insulating wires at predetermined intervals, and the diameter of the insulating wires is larger than the diameter of the conductive wires, and a step of a certain height is naturally formed between them, which can avoid short-circuit burnout due to contact between the conductive metal filament and the internal channel, and at the same time can enhance mass transfer and accelerate the discharge of products, the flexible braided electrode has a hollow mesh cylindrical structure, which can achieve combined cleaning of the inside and outside and improve the cleaning effect, during polishing the flexible braided electrode can adaptively bend and deform to conform to the curved internal channel, and by utilizing its in-and-out-out penetration characteristics, it can perform combined cleaning of the inside and outside, and by combining this with the rotation and reciprocating motion of the electrode, it can achieve electrochemical polishing of complex internal channels, and the flexible braided electrode provided by this application, when combined with an innovative method, can achieve highly efficient and high-quality finishing of complex internal channels.
