Auger Electron Spectroscopy and Rutherford Backscattering Studies of Copper in 2024-T3 Aluminum Following Electrochemical Anodization in Phosphoric Acid.
Abstract
The effects of the electrochemical anodization of deoxidized 2024-T3 aluminum on copper were characterized by Auger electron spectroscopy and Rutherford backscattering. Anodization was performed in phosphoric acid at constant potential. Data is presented which shows that constant potential. Data is presented which shows that constant potential anodization of 2024-T3 is more efficient than aluminum in terms of oxide growth rates for short anodization times. However the maximum anodic oxide thickness achievable on the alloy is less than the pure metal. Copper is shown to be enriched at the oxide metal interface because of its diffusion from the bulk during anodization. The presence of copper at the oxide-metla interface is shown to affect oxide morphology. (Author)
