【摘要】：在慣性約束聚變研究中,硼的柱形微靶可作為黑腔填充材料。本文通過(guò)電火花銑削加工技術(shù),采用含碳較高的電介質(zhì),利用導(dǎo)電性能較好的鎢鋼作電極材料,實(shí)現(xiàn)了半導(dǎo)體硼柱形微靶加工。通過(guò)奧林巴斯測(cè)量顯微鏡對(duì)硼柱直徑進(jìn)行了測(cè)量,測(cè)量結(jié)果表明,硼柱的直徑加工精度可控制在小于±10μm。采用掃描電鏡對(duì)形貌進(jìn)行了分析,結(jié)果表明,加工前后硼的表面形貌未改變。通過(guò)能譜分析了硼柱表面的導(dǎo)電層成分及通過(guò)X射線能譜(XPS)分析了碳元素價(jià)態(tài),結(jié)果表明,電火花銑削加工過(guò)程中,由于電介質(zhì)分解生成游離態(tài)的碳及電極材料熔融后沉積在硼表面,形成輔助導(dǎo)電層,通過(guò)對(duì)輔助導(dǎo)電層加工,產(chǎn)生的瞬時(shí)高溫使硼熔融氣化,從而實(shí)現(xiàn)對(duì)半導(dǎo)體硼的加工。
[Abstract]:In inertial confinement fusion, boron columnar targets can be used as black cavity filling materials.In this paper, semiconductor boron columnar microtarget machining is realized by means of EDM technology, using dielectric with high carbon content and tungsten steel with good conductivity as electrode material.The diameter of boron column was measured by Olympus measuring microscope. The results show that the machining accuracy of boron column is less than 鹵10 渭 m.The morphology of boron was analyzed by scanning electron microscope. The results showed that the surface morphology of boron remained unchanged before and after processing.The composition of conducting layer on the surface of boron column was analyzed by energy spectrum, and the valence state of carbon element was analyzed by X-ray energy dispersive spectroscopy (XPS). The results show that, in the process of EDM,Due to the decomposition of dielectric and the deposition of free carbon and electrode materials on the surface of boron after melting, the auxiliary conductive layer is formed. By processing the auxiliary conductive layer, the boron is melted and vaporized by the instantaneous high temperature, thus the processing of semiconductor boron is realized.
