Hydrogen Peroxide Corrosion on Carbon Steel
On the Corrosion of Carbon Steel by Hydrogen Peroxide
Carbon steel is a commonly used material, but when it encounters hydrogen peroxide, it is often at risk of corrosion.
Hydrogen peroxide is highly oxidizing. Carbon steel contains elements such as carbon iron. When it encounters hydrogen peroxide, its oxidizing iron-causing elements are oxidized. Iron loses electrons and dissolves into ferrous ions into the solution, such as the beginning of the electrode reaction. Ferrous ions may be further oxidized into iron ions, which is a sign of deepening corrosion.
The structure of carbon steel is also changed due to corrosion. The originally tight lattice is caused by the loss of iron, resulting in internal defects. From a microscopic perspective, there are pits and cracks on the surface. Over time, the pits gradually increase, and the cracks spread, causing the mechanical properties of carbon steel to deteriorate. Its strength and toughness are both reduced, making it unusable.
Furthermore, environmental factors also affect corrosion. When the temperature rises, the reaction rate increases, and the corrosion intensifies; the pH of the solution changes, which also affects the corrosion process. Acidic environment, or promotes the dissolution of iron ions; alkaline is too strong, although it is partially inhibited, it will also damage carbon steel in the long run.
To prevent hydrogen peroxide from corroding carbon steel, a protective layer can be coated, such as corrosion-resistant paint, to prevent hydrogen peroxide from contacting carbon steel; or carbon steel materials with excellent corrosion resistance can be selected to resist corrosion.
To sum up, knowing the principle of hydrogen peroxide corroding carbon steel and seeking protection methods can ensure the long-term durability of carbon steel, and make the best use of it in industrial affairs.
