Abstract
With the purpose of forming an anodic oxide coating that is given conductivity or other new functions on the surface of aluminum-based material with high productivity, anodizing of aluminum-based material ( ) is performed in an anodizing bath containing sulfuric acid together with nitrate ion to form a porous anodic oxide coating on the surface of the aluminum-based material ( ). In another processing step, if electroplating is performed after anodizing, silver or a silver compound or other metal ( ) can be electroplated from an electroplating bath without dissolving and removing the barrier layer from the bottom ( ) of the pores ( ) of the porous anodic oxide coating ( ).
