    摘要:

    為探索沉積態(tài)貧鈾（DU）薄膜更有效的防護層新材料與更薄的防護層制備技術(shù)，開展了納米Al涂層的磁控濺射制備技術(shù)研究，制備了Al與DU單層、Al/DU/Al三層薄膜樣品并開展了納米Al防護層Al/DU/Al樣品大氣環(huán)境下72h的防氧化性能研究。利用掃描電鏡（SEM）觀察樣品表面形貌，X射線光電子能譜儀（XPS）測量樣品元素組成與價態(tài)變化，X射線衍射（XRD）測量樣品物相組成與變化。結(jié)果表明：厚度大于10nm即可生成連續(xù)的Al涂層，Al涂層晶粒隨著厚度增加呈現(xiàn)長大的趨勢；30nm厚Al防護涂層有效阻止了DU薄膜大氣環(huán)境的氧化：72h內(nèi)，DU層O含量沒有發(fā)現(xiàn)明顯的變化。

    Abstract:

    In order to investigate more effective and thinner protective coatings preparation for uranium laser targets, nano-Al coatings prepared by magnetron sputtering were researched, single-layer of Al and DU, Al/DU/Al “sandwich” film samples were prepared, oxidation resistant of nano-Al coatings Al/DU/Al samples under atmosphere environment was investigated. The surface topography, atomic concentration and atomic concentration’s change, and phase composition of these samples were characterized by SEM, XPS and XRD. The results show: Al coating becomes continuous when its thickness exceeds 10 nm, grain size of Al coatings increase with thickness. 30 nm thick Al protective coating effectively avoids DU layer oxidation, no obvious increase of DU layer’s oxygen content under atmosphere environment was found within 72 hours.
