In-situ electrochemical cell device capable of measuring electrochemical corrosion performance under electromagnetic field

Abstract

The invention belongs to the technical field of electrochemistry, and discloses an in-situ electrochemical cell device capable of measuring electrochemical corrosion performance under an electromagnetic field. An inner-layer electrolytic reaction tank is accommodated in an outer-layer water bath layer; an electromagnetic coil device sleeves outside the outer water bath layer; a water outlet and awater inlet are respectively formed in the upper and lower parts of the outer water bath layer; a reference electrode port, an air inlet, a working electrode port, an auxiliary electrode port and an air outlet are formed in the inner-layer electrolytic reaction tank; the working electrode port extends into the inner-layer electrolytic reaction tank through a working electrode pipeline, and the bottom of the working electrode pipeline is positioned in the center of the whole inner-layer electrolytic reaction tank. The in-situ electrochemical cell device is simple in structure, convenient to process and easy to operate in experiments. A common quartz material in the market is adopted as a cell body, the raw material is easy to obtain, and the cost is low. Three electrodes are inserted into the reaction tank through perforated rubber plugs, and connectors are frosted ports, so that the three electrodes are convenient to insert, fix, take out and clean.

Description

technical field [0001] The invention belongs to the technical field of electrochemistry, and in particular relates to an in-situ electrochemical cell device capable of measuring electrochemical corrosion performance under an electromagnetic field. Background technique [0002] Corrosion of metals is a very common phenomenon at present. No matter what the working environment is, metals will be more or less corroded, and there are many factors affecting corrosion. As the use of electrical appliances becomes more and more popular, our lives are also surrounded by various electromagnetic fields, so what effect does the existence of electromagnetic fields have on the corrosion of metal materials? In response to this problem, more and more people at home and abroad have begun to conduct research on electromagnetic fields. Electrochemical method is an important method for the study of corrosion behavior, which can reflect the corrosion performance of materials to a large extent. ...

Problems solved by technology

[0003] (1) In the prior art, the working electrode is not fixed, and it cannot be ensured that the working electrode is at the same position in each experiment. The position is different, and the magnitude of the magnetic field force is also different, which will seriously affect the accuracy of the measurement data sex, seriously affecting judgment

[0004] (2) The temperature and dissolved oxygen of the experimental solution cannot be directly changed while the electromagnetic field is applied, the test conditions are single, and multi-functional use cannot be achieved

[0005] (3) The structure is complex, and it takes time and effort to build an experimental platform
