[Technical Column] Issue 9: The Corrosion Resistance of Aluminum Sheet Materials and a Discussion on Heat Exchangers
Corrosion prevention methods are differentiated based on the design policy of heat exchangers and the environment in which they are used!
In this column, following the 8th installment, I will discuss how to protect a heat exchanger from perforation due to pitting corrosion and gas leaks for 15 years using an extremely thin aluminum tube with a thickness of 0.2mm. Metals each have their own electrochemical potential, and when different metals come into contact, the metal with the lower potential tends to corrode preferentially. For example, between zinc and iron, zinc has a relatively low potential, so it corrodes preferentially while iron remains unaffected during that time. This principle is utilized in the outer walls of ships, where a zinc coating is applied to the iron body to prevent salt damage from seawater. Similarly, galvanized steel sheets are coated with zinc to prevent the corrosion of iron, and they are widely used in buildings and structural materials. *For more details about the column, please refer to the related links.
