Abstract
The rates of cathodic reduction of oxygen and hydrogen peroxide were compared for rusted lowalloy steel and mild steel by using the potential sweep method in neutral solution of 1M sodium sulfate.
The apparent reduction current of hydrogen peroxide decreased as the amount of rust-oxide increased by longer outdoor exposure, especially over thirty days.
It can be concluded that the rust layer formed on low-alloy steel shows greater contribution to the retardation of further atmospheric corrosion than does the rust on mild steel.
