铝 (Al) 的电解抛光已用于形成各种形态和尺寸的表面纳米图案。然而，晶体取向对电解抛光铝中纳米图案形态和尺寸的影响尚不清楚。在这里，退火的多晶和单晶铝样品在高氯酸、乙醇、丁基溶纤剂和水的电解质中在 40 V 下进行电解抛光，通过系统的 EBSD 和 SEM 检查牢固地建立了晶体取向与纳米图案形态和尺寸之间的相关性。纳米图案形态和纳米图案尺寸的异质性是由晶粒的晶体各向异性引起的。对于以不同的取向角相对于每个主方向 [101]//ND、[101]//ND 和 [111]//ND 取向的晶粒和平面，纳米图案的形态和尺寸逐渐变化。对于具有几乎相同的取向差角的晶粒表面平面，也会发生纳米图案形态之间的转变。纳米图案形态和尺寸的表面结构敏感性得到了牢固的确立，然后通过调用阶梯台和阶梯壁架表面结构模型以及基于已报告的理论模型开发精细的吸附扩散视角来定性解释。这里报告的发现对于获得电解抛光铝和其他金属中纳米图案形态和纳米图案尺寸的晶体取向依赖性的新见解具有重要意义。
Electropolishing of aluminum (Al) has been applied to form surface nanopatterns of various morphologies and sizes. However, the effect of crystallographic orientation on nanopattern morphology and size in electropolished Al is unclear. Here, annealed polycrystalline and monocrystalline Al samples were electropolished at 40 V in an electrolyte of perchloric acid, ethanol, butyl cellusolve and water, the correlation between crystallographic orientation and nanopattern morphology and size was firmly established through systematic EBSD and SEM examination. Heterogeneity in nanopattern morphology and nanopattern size is induced by crystallographic anisotropy of grains. Nanopattern morphology and size change gradually for grains and planes oriented with varying misorientation angles against each primary direction [101]//ND,[101]//ND and [111]//ND. The transitions between nanopattern morphologies also occur for grain surface planes with near identical misorientation angles. The surface structure sensitivity of nanopattern morphology and size was firmly established and then qualitatively explained by invoking step-terrace and step-ledge surface structure models and by developing a refined adsorption-diffusion perspective based on a reported theoretical model. The findings reported here contribute significantly to gaining new insights into the crystallographic orientation dependence of nanopattern morphology and nanopattern size in electropolished Al and other metals.
