摘要	The corrosion morphologies of as-extruded magnesium alloy AM60 in 3.5%NaCl aqueous solutions with pH 3, 7 and 12 were observed, and the number and size of corrosion pits were measured. The effect of pH values on corrosion of AM60 and the role of AlMn particles in corrosion were discussed. A corrosion model of AM60 was put forward. The experimental results indicate that the pitting corrosion occurred in an acidic or neutral 3.5%NaCl aqueous solution, the pits initiated in the alpha matrix around AlMn particles, whereas Al element was dissolved in the rich-Al areas such as AlMn particles and beta phase, and the honeycomb morphology was formed on the surface in alkaline solutions. The number of corrosion pits is most at pH 7.
