用多次扫描循环极化法研究经离子束表面改性的Ni_3Al(0.1B)在H_2SO_4溶液中的腐蚀行为。电化学测试和表面形貌的观察结果表明,离子注入、离子束混合和离子束辅助沉积技术对减缓Ni_3Al(0.1B)在用氧气饱和的1N H_2SO_4溶液中的腐蚀和改善钝化性能很有效果。
The corrosion behavior of Ni_3Al(0.1B) treated with different ion beam techniques has been characterized by multi-sweep-cyclic-voltammetry and optical microscopy. The results revealed that the ion implantation, ion beam mixing and ion beam assisted deposition are very effective to reduce the corrosion rate, to improve the passivability and to increase the durability of specimens in 1N H_2SO_4 solution saturated with oxygen.
