    Abstract
  • Adipic-sulfuric acid anodic oxidation was improved by adding hexane diacid into sulfur acid anodic bath solutions for LY12CZ aluminum alloy, and compared to conventional sulfur acid anodic oxidation. The morphology of two kinds of oxide films was observed by using filed emission-scanning electron microscope (FE-SEM). The corrosion resistance and electrochemical character of oxide film were investigated with electrochemical impedance spectroscope (EIS). Tensile fatigue test of anodic LY12CZ plates was carried out. It is found that adipic-sulfuric acid oxide film has smaller pore structure and fewer defects, and it has better stability and corrosion resistance in corrosive environment. The influence of anodic oxidation on the fatigue properties decreases. The mechanism of adipic-sulfuric acid anodic oxidation was also discussed.
