Unexpected higher corrosion in the gas phase region of metals caused by calcium and magnesium ions compared to sodium ions

“…54 Compared with the aqueous solution and ethanol, MgCl 2 has lower binding energy in ethanol. 55 Considering the solubility of magnesium chloride molecules in ethanol and the volatility of ethanol, ethanol carried Mg 2+ ions to the gas-phase region of the iron surface during semi-immersion of the circular samples, and exposure to air with a higher oxygen content accelerated the degree of corrosion. Compared to NaCl molecules, MgCl 2 molecules have a stronger complexing ability with ethanol molecules.…”
