摘要：

Superior corrosion resistance was obtained for Fe-56+-IBD (ion beam deposited) films on Si and Ge substrates. The iron films deposited at an ion energy of 50 eV showed the highest corrosion resistance in 0.001 M NaCl solution. The estimated current density at its corrosion potential was four orders of magnitude smaller, 10(-6) A/m2, than that of 2N-purity iron bulk materials. Ion bombardment induced formation of finely-grained polycrystalline structure, and coupled with its purifying action, these were considered to account for the superior corrosion resistance.
