Problems solved by technology
However, the spring abutment point contact is easy to cause poor contact of the electrode working circuit
At the same time, under the action of alternating stress, the spring is prone to plastic deformation, fatigue fracture and stress corrosion fracture during the corrosion detection process, which directly leads to the failure of the working electrode

Description
technical field [0001] The invention belongs to the technical field of electrochemical corrosion testing, and in particular relates to a working electrode for corrosion detection, and also relates to a preparation method of the working electrode. Background technique [0002] Electrochemical corrosion tests generally use a three-electrode system, which consists of an auxiliary electrode, a reference electrode and a working electrode. The working electrode is the object of the corrosion test research, and the primary task of the corrosion test is to prepare the working electrode. The production of the working electrode not only requires a simple structure and process, good contact of the electrode system circuit, but also avoids corrosion test interference caused by incomplete packaging of the gap.
