Abstract
The atmospheric corrosion behavior of AZ91D magnesium alloy were studied by means of the outdoor exposure in Beijing atmosphere. The average corrosion rates of AZ91D were calculated by using weight loss method. Many methods, such as metallographic examination, SEM, XRD, EDS, IR were employed to analyze the surface properties (such as morphology, composition and structure) of the atmospheric corrosion products of AZ91D. The result of the outdoor exposure shows that AZ91D magnesium alloy is resistant to atmospheric corrosion, compared with A3 steel. The atmospheric corrosion of AZ91D magnesium alloy is a localized corrosion.
