| 摘 要： | 通过测试电子铝箔在HCl-AlCl3中阳极极化曲线和电解腐蚀隧道孔的极限长度,发现了隧道孔的极限长度llim与铝箔的点蚀电位与自腐蚀电位的差值ΔE存在相关性,导出了隧道孔生长的动力学公式以及?E与llim的线性关系式,表明通过测试ΔE可以判断llim的变化趋势,为研究新型发孔液提供了一种简便的途径。

| Abstract: | Both of the anodic polarization curves and the limiting lengths, llim of electro-etching tunnels of electronic Al foil electro-etched in the HCl-AlCl3 were measured. It was found that there was a correlation between the llim and the potential different value, ΔE, of pit corrosion potential and corrosion potential of Al foil. The dynamic equations on tunnel growth and the linear quantitative correlation between llim and ΔE were deduced. Therefore, the change tendency of llim is judged simply by measuring ΔE, which supplies a convenient way to study the new kind of tunnel-forming etchant. |
