Chain link chemical corrosion refers to the corrosion caused by the direct chemical reaction between steel and surrounding media. Most corrosion is oxidation, which results in loose oxides on the steel surface. It is lax and easy to split. Harmful media can further enter and react to cause corrosion. In a dry environment, corrosion develops slowly, and the degree of reaction increases with increasing temperature and humidity.
Chain link mesh electrochemical corrosion is caused by the primary battery on the gold surface. Steel itself contains iron, carbon and other components. Because of the different electrode potentials of these components, many microbatteries are formed. In humid air, a thin film of water is adsorbed on the steel surface. In the anode area, iron is oxidized to Fe 2+ and enters the water film. Due to the dissolved oxygen in the water, the oxygen in the cathode area is reduced to OH. The two oxides combine to form insoluble Fe (OH) 2, which is further oxidized into loose and easily peeled red-brown rust (OH) 3.
