[Abstract]:In order to improve the surface wear resistance and corrosion resistance of 6061 aluminum alloy, anodic oxide film was prepared in oxalic acid electrolyte by anodizing technology. The microhardness of the film was measured by microhardness tester, the friction and wear properties of anodic oxide film were studied by friction and wear tester, and the corrosion resistance of anodic oxide film was analyzed by electrochemical impedance spectroscopy (EIS). The effects of anodizing current density, electrolyte temperature and anodizing time on the hardness, wear resistance and corrosion resistance of the oxide film were studied. The anodizing temperature is 10 鈩，
