Studies were made of the corrosion behaviour bymulti-sweep cyclic voltammetry and optical microscopy. The corrosion resistance of the spec-imen after implanting by Mg~+ ions may be much improved to 0.5mol/L H_2SO_4 solution.Experimental measurements and computer simulation were carried out on the segregation ofMg atoms at the grain boundaries. Mechanism of beneficial effect of Mg~+ ion implantationon corrosion resistance was approaching.
