Abstract

Corrosion behavior of AZ91 magnesium alloy under NaCl particle deposition condition was investigated by gravimetric method and surface analysis technique. It was found that the mass gain increased rapidly at the beginning of exposure and then slowly with time. The corrosion morphologies were observed and the results showed that NaCl deposition resulted in the occurrence of localized corrosion. The composition of corrosion product was analyzed using X-ray photo electron spectroscopy. It was suggested that the corrosion product was a mixture of oxide and hydroxide of magnesium and aluminum.
