摘要

用扫描电子显微镜研究了室温下氦离子辐照Fe77Ni5B18等 10种非晶态合金的表面形貌。氦离子的能量为 4 0keV和 6 0keV

总注量为 1.0× 10 18— 4 .0× 10 18He/cm2 。对于不同的注量和不同的材料

观察到了层离、发泡、剥落、发泡破裂、二代发泡和多孔结构等多种表面损伤类型。测量了泡的直径和剥落泡皮的厚度

并讨论了表面损伤类型和初现的临界注量与材料种类和离子能量的关系。

Abstract

The blistering and flaking behavior of many kinds of amorphous alloys under helium ion bombardment at room temperature has been investigated. Helium ions with energies of 40keV and 60keV were implanted to the dose range 1.0×10 18-4.0×10 18 ions/cm 2. The surface topography of samples after irradiation was observed by using a scanning electron microscope. The diameter of blister and the thickness of exfoliated blister lids were measured. The results showed that many kinds of surface topography characteristics appeared for different doses

energies and amorphous alloys

such as flaking

blistering

exfoliation

blister rupture

second-generation blistering and porous structure. The dependence of surface damage modes and the critical dose for onset of blistering and flaking on material sort and ion energy was discussed.
