Role of Metal Cations on Corrosion of Coated Steel Substrate in Model Aqueous Layer

Effects of NH4+, Na+, and Mg2+ ions on the corrosion behavior of galvanized steel in wet–dry cyclic conditions

“…The electronic conductivity of ZnO promotes oxygen reduction, which is a common cathodic reduction reaction. [8][9][10][11][12] Hydroxide ions from oxygen reduction reaction adsorbed on the film on electrochemical reaction with Cl − , SO x , and CO 2 form rust layer. [12][13][14] The rust layer composition depends on the exposure condition, type and level of pollutants, and the number of wet-dry cycles.…”

Hydrogen Permeation Behavior of Scratch on Zn Coated Steel during 1000 Hours Wet and Dry Corrosion Test

“…Islam et al reported that Zn 2 + in the solution easily forms thin Zn protective layer on the steel surface after immersion test. 16,17) It is seemed that a thin Zn protective layer existed on the scratch. AES surface analysis which can measure the thin surface layer was carried out.…”

Hydrogen Permeation Behavior of Scratch Formed on Zn Coated Steels in Simulated Atmospheric Corrosion Environment

“…Islam et al reported that Zn formed thin protective layer on steel surface after immersion test. 25,26) This thin Zn protective layer may inhibit corrosion reaction and hydrogen entry. Igarashi et al reported that hydrogen permeation current after laser irradiation in the aqueous solution containing Zn 2 + was smaller than that in the solution containing Na + or Mg + .…”
