Effect of Corrosion Resistance and Rust Characterization for Hydrogen Absorption into Steel under an Atmospheric Corrosion Condition

Abstract

Hydrogen absorption into steel under an atmospheric corrosion condition is considered to occur because of the H⁺ ion is reduced to hydrogen atom (H_ads) receiving electron formed by rust that forms by the corrosion reaction on steels. Thus, we investigated whether it is possible to reduce the amount of hydrogen absorption into steels by adding elements that improve corrosion resistance and control the formation of rust to reduce corrosion reaction. It was discovered that the amount of hydrogen absorption into steels can be reduced by adding elements that improve corrosion resistance and control the formation of rust on the surface of steels.
