| 摘 要： | 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

| Abstract: | Dose of 1×10~(16) Mg~+ ion / cm~2 with 120 keV was implanted into theintermetallic compound Ni_3Al(0.1B). 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. |
