摘要：

120 keV Mg ions to a dose of 1 X 10(16) ions/cm2 were implanted into the intermetallic compound Ni3Al(0.1B). The corrosion behavior was characterized by multisweep cyclic voltammetry and optical microscopy. The results showed that Mg ion implantation is very effective to improve the corrosion resistance of the specimen in a solution of 1N H2SO4. Experimental measurements and computer simulation were carried out for study of segregation behavior of Mg atoms at the grain boundaries. It leads to an improved understanding of the mechanism of beneficial effect of Mg ion implantation on corrosion behavior.
