Abstract

Abstract

Effect of sea atmospheric environment and industrial atmospheric on corrosion of metal Zn has been studied for the first time using Quartz Crystal Microbalance(QCM) combined with Infrared Transmissive Spectroscopy(IRTS). QCM results have shown that NaCl deposited on surface of zinc is the most corrosive electrolyte among selected electrolytes to atmospheric corrosion of zinc, (NH₄)₂SO₄ deposited on the surface of zinc is the second, NaNO₃ weak, and Na₂CO₃ the slightest. Combined with the IRTS analysis of the corrosion products, the corrosion mechanism of Zn under thin liquid film has elaborated.
