Abstract

This study is intended to present an efficient methodology for optimizing the anodic polarization process of 6xxx aluminum alloy to have high hardness. Additional electrochemical experiments have been conducted to observe the corrosion behavior of these oxide films. LÇorthogonal array with four factors at three levelsareused. The type of additive, electrolyte temperature, current density and dissolved aluminum ions are chosen as parameters. The results show that the main parameters to increase the hardness of the oxide films are electrolyte temperature, additive type, dissolved aluminum ions and current density, respectively. After anodization, the pores of the oxide film are sealed and their surface morphologies are observed by using scanning electron microscopy. Then, the corrosion potentials of these oxide films are measured to define their electrochemical behaviors to evaluate their possible uses in advanced technology.
