接着性および耐食性に優れたA5052アルミニウム合金への陽極酸化処理

抄録

For this study, we investigated anodization to improve the adhesion and corrosion resistance of A5052 aluminum alloy. Sulfuric acid anodization was found to have excellent corrosion resistance but poor adhesion. Phosphoric acid anodization showed excellent adhesion but poor corrosion resistance. Two-step anodization with phosphoric acid anodization and sulfuric acid anodization produced both excellent adhesion and corrosion resistance.
