When metal is in contact with the surrounding medium, metal damage caused by chemical or electrochemical action is called metal corrosion. Metal corrosion is very common, such as rusting of steel parts in humid air, and steel during heating. Oxide film, underground metal pipe is subject to corrosion and perforation, corrosion of chemical machinery in strong corrosive media, white powder produced by the surface of aluminum products used in humid air. After the metal is corroded, it will change or not be used in terms of shape, color and mechanical occurrence. It is therefore extremely important to understand corrosion and take protective measures. Concerned about surprises Label: What is metal corrosion?
