英文摘要In this work, the microstructure and corrosion resistance of phosphate conversion coatings on the cross-sectional surface (CS), the rolled surface (RS) and the slanted surface (SS) of rolled AZ31 magnesium alloy were compared. Results demonstrate that most grains on the rolled surface (RS) conform (0001) orientation, which renders a lowest electrochemical reactivity; while the cross-sectional surface (CS) and the slanted surface (SS) exhibited a preferential orientation of (0110) and (1210), which renders a higher electrochemical reactivity. The variation of electrochemical reactivity affects the nucleation rate of crystals, thus altering the compactness and corrosion resistance of phosphate conversion coating on different surfaces. The conversion coating on the RS exhibits the worst corrosion resistance.
