Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrochemical measurement technology, and in particular to a thin-film electrochemical measurement device based on metal corrosion simulation. Background Technology
[0002] A thin liquid film on the surface of a metallic material can cause thin-film electrochemical corrosion, a common corrosion phenomenon in both natural and industrial environments. Atmospheric corrosion is a typical example of thin-film corrosion. In a humid environment, the temperature difference between the metallic material and the surrounding environment causes moisture in the air to condense on the metal surface, forming a thin liquid film of a certain thickness. When this film reaches a thickness of several tens of water molecules or more, the conditions for an electrochemical reaction occur, leading to thin-film electrochemical corrosion. Changes in environmental humidity and temperature alter the thickness of the thin liquid film on the metallic surface. This variation in film thickness affects the diffusion of corrosive media within the film, thus influencing the electrochemical corrosion process.
[0003] Traditional electrochemical corrosion testing methods typically measure the thickness of the thin liquid film already formed on the surface of the metal material. However, there is a lack of a device that can adjust and control parameters such as the thickness of the electrolyte, ion concentration, temperature, and voltage to study different reaction mechanisms during the corrosion process.
[0004] Therefore, it is necessary to invent a thin-film electrochemical measurement device based on metal corrosion simulation to solve the above problems. Utility Model Content
