在金属间化合物Ni_3Al(0.1B)中注入能量为120keV,剂量为1×10~(16)ion/cm~2的Mg~+离子用多次扫描循环极化曲线测量和光学显微镜观察研究其腐蚀行为.发现经Mg~(+)离子注入后的样品在0.5mol/L H_2SO_4溶液中的抗蚀性能有很大的改善对Mg原子的偏聚现象进行实验测试和计算机模拟,增进了对Mg~(+)离子注入提高金属间化合物抗蚀性能机制的了解 The Mg ~ + ions with energy of 120keV and dose of 1 × 10 ~ (16) ion / cm ~ 2 were implanted into the intermetallic compound Ni_3Al (0.1B) and the corrosion of the Mg ~ + ions was observed by the multi-cycle scanning polarization curve and optical microscope The corrosion resistance of the samples after the implantation of Mg ~ (+) ions in 0.5 mol / L H 2 SO 4 solution was found to be greatly improved. The experimental study and computer simulation of the segregation of Mg atoms were also conducted. (+) Ion Implantation to Improve the Mechanism of Corrosion Resistance of Intermetallics
