Description

technical field

[0001] The invention relates to an electrode device for in-situ research on the atmospheric corrosion process under liquid droplets. Background technique

[0002] With the rapid development of the global ocean strategy in recent years, the materials used in the marine environment have been more seriously challenged. Especially in the marine atmospheric environment, aerosols have an important effect on the surface of materials, and have a serious impact on their service life.

[0003] Atmospheric corrosion of metal under liquid droplets is an important form of atmospheric corrosion, especially for buildings or metal facilities near the coastline, causing great damage. Atmospheric corrosion involves the complex process of gas / liquid / solid and its interface, so many factors can affect its corrosion process. Atmospheric corrosion is essentially an electrochemical process. The droplets condensed on the metal surface are the main cause of atmospheric corrosion of...
