Influences of Micro-Arc Oxidation on Pre-Corroded Fatigue Property of Magnesium Alloy AZ91D

Abstract:

The surface morphologies of micro-arc oxidation coatings and chemical oxidation coating formed on AZ91D alloy were observed by scanning electron microscopy. The fatigue properties of both specimens with micro-arc oxidation coatings and chemical oxidation coating after the pre-corroded treatments in neutral salt spray test were investigated comparatively. The result shows that pre-corrosion treatment decreases the fatigue life, but the pre-corroded fatigue life of specimens with chemical oxidation is lower than that with micro-arc oxidation. The thickness of micro-arc oxidation coatings has no obvious influence on the pre-corroded fatigue life of AZ91D alloy.
