【摘要】：強(qiáng)脈沖離子束作為一種閃光熱源在材料表面改性方面具有廣泛的應(yīng)用.燒蝕效應(yīng)對(duì)于強(qiáng)脈沖離子束與物質(zhì)相互作用以及強(qiáng)脈沖離子束薄膜沉積過程具有重要的影響.因此,分析強(qiáng)脈沖離子束的燒蝕過程和機(jī)理對(duì)于優(yōu)化其應(yīng)用具有重要意義.為了研究強(qiáng)脈沖離子束的燒蝕產(chǎn)物特性,采用1.2—1.5 J/cm~2的強(qiáng)脈沖離子束輻照純鋅靶材,并使用單晶硅片收集輻照過程中產(chǎn)生的燒蝕產(chǎn)物.通過掃描電子顯微鏡、能譜儀和高精度天平的分析與測(cè)量,得到了燒蝕產(chǎn)物的表面形貌和相關(guān)特性等實(shí)驗(yàn)結(jié)果.結(jié)合實(shí)驗(yàn)和有限元模擬計(jì)算得到的材料表面溫度場(chǎng)分布演化結(jié)果,可以證明在強(qiáng)脈沖離子束輻照鋅靶材的燒蝕過程中會(huì)有氣態(tài)、液態(tài)和固態(tài)三種不同狀態(tài)的燒蝕產(chǎn)物產(chǎn)生.
[Abstract]:As a flash heat source, strong pulsed ion beam has been widely used in surface modification of materials. The ablation effect plays an important role in the interaction of strong pulsed ion beam with matter and the deposition process of strong pulsed ion beam film. Therefore, it is important to analyze the ablation process and mechanism of intense pulsed ion beam for optimizing its application. In order to study the characteristics of ablation products of intense pulsed ion beams, 1.2-1.5 J/cm~2 intense pulsed ion beams were used to irradiate pure zinc targets, and monocrystalline silicon wafers were used to collect ablative products produced during irradiation. Through the analysis and measurement of scanning electron microscope, energy spectrometer and high precision balance, the surface morphology and related properties of ablative products were obtained. Combined with the results of experimental and finite element simulation, it can be proved that there are three kinds of ablation products in different states of liquid and solid in the ablation process of zinc target irradiated by strong pulsed ion beam.
