Abstract

Anodization technology allows for the rapid and controlled preparation of specified regular nanostructures on the surface of metal. During anodization, the metal ions migrating outward and the oxygen ions provided by the electrolyte form oxides at the metal/electrolyte interface, and the migration rate of different kinds of metal ions is different, which leads to the complex mechanism of the anodization of alloys. This work focused on the mechanism of the anodization of alloys, and studied the effects of hydroxide ions in electrolyte and applied voltage on the reactivity of different components of brass. It was obtained that low voltage favors the migration of Zn and high KOH concentration favors the dissolution of the anodic products of Cu, so that an alloy with Zn content of 16.05% was obtained when a voltage of 40 V was applied, and when a voltage of 60 V was applied, the alloy with Cu content of 13.34% was obtained in 0.4 M KOH solution.

影响成分和结构的因素和机制：黄铜（Cu0.64Zn0.36）合金在碱性溶液中的阳极氧化处理

阳极氧化技术可以快速、可控地在金属表面制备特定的规则纳米结构。在阳极氧化过程中，向外迁移的金属离子和电解质提供的氧离子在金属/电解质界面形成氧化物，而不同种类金属离子的迁移速率是不同的，这就导致了合金阳极氧化的复杂机理。本研究以合金的阳极氧化机理为重点，研究了电解液中氢氧根离子和外加电压对黄铜不同成分反应性的影响。结果表明，低电压有利于锌的迁移，高浓度的 KOH 有利于铜阳极产物的溶解，因此，在 0.4 M KOH 溶液中，当施加 40 V 电压时，可获得锌含量为 16.05% 的合金；当施加 60 V 电压时，可获得铜含量为 13.34% 的合金。
