Description

technical field [0001] The invention relates to the technical field of metal electrochemical corrosion, in particular to an image-based high-throughput characterization experimental device for metal corrosion. Background technique [0002] Metal materials will undergo electrochemical corrosion through electrode reaction in the electrolyte solution. Electrochemical corrosion of metals is very common. It will significantly reduce the mechanical properties of metal materials such as strength, plasticity, and toughness, destroy the geometry of metal components, and increase the gap between parts. wear and tear, shorten the service life of the equipment, and even cause catastrophic accidents such as fire and explosion. [0003] According to the different physical and chemical properties of the metal itself, the form of corrosion is also different, including: pitting corrosion, stress corrosion, uniform corrosion, wear corrosion, etc. In different corrosive media, the corrosion f...
