Surface characteristics of bulk metallic glasses as first mirror materials for fusion veactor
摘要
Abstract
Surface characteristics of mirrors made from polycrystalline Mo, bulk metallic glasses(BMGs) Zr65 Al7.5 Ni10Cu17.5 and Co61.2 B26.2 Si7.8 Ta4.8 were studied. The mirrors were exposed to H plasma in an unbalanced magnetron sputtering chamber. The results show that with increasing the H plasma sputtering time, surface roughnesses of the mirrors made from polycrystalline Mo and BMG Zr65 Al7.5Ni10Cu17.5 increase and their specular reflectivities decrease; whereas the surface roughness reduces and the reflectivity increases for the mirror made from BMG Co61.2B26.2Si7.8Ta4.8. During H plasma sputtering, the surface state of BMGs can self-repair. Taking into account the evolution of optical properties after sputtering, amorphous metal Co61.2B26.2Si7.8Ta4.8 can best withstand the erosion conditions and preserve its optical properties.关键词
