摘要: 采用电化学和光电子技术,研究了N~+离子束轰击对Fe/Cr、Fe/Al系在水溶液巾腐蚀行为的影响。分别用真空沉积和离子溅射技术在纯铁上沉积Cr(400(?))或Al(800(?)),然后经N~+离子束轰击(能量为150keV,剂量为5×10~(16)N~+/cm~2)。轰击后Fe/Cr、Fe/Al样品的阳极极化曲线的致钝电流密度和维钝电流密度均降低了一个数量级。其主要原因是N~+离子注入的化学效应和亚稳相氮化物的形成。这种亚稳相的氮化物作为阻挡层,阻止了基体金属的阳极溶解过程。

Abstract：The effects of N~+ ion beam bombardment on the aqueous corrosion bebaviour of Fe/Al and Fe/Cr system,have been investigated by means of electrochemical and electron-optical techniques. Fe deposited with Al (800(?)) and Cr (400(?)) were bombarded by a N~+ ion beam with an energy of 150 KeV at the dose of 5x10~(6)N~+/cm~2. Anodic current Ic and Im on anodic polarization curves for both Fe/Al and Fe/Cr systems were decreased by one order of magnitude, it is mainly related with the chemical effect of N~+ ion implantation,and presumably associated with formation of a metastable phase of nitride as a barrier layer reducing the anodic dissolution.
