Abstract
An anodic oxide film is formed on an aluminium or aluminium alloy work piece by forming an anodic oxide film on the work piece by AC electrolysis followed by subjecting the work piece to DC electrolysis. The AC anodizing step may be conducted at a voltage of 5 to 30V for 30 seconds to 10 minutes and the DC anodizing step may be conducted at a voltage of 5 to 30V for a period of 1 to 20 minutes. The anodic oxide coating is suitable for adhesive bonding of aluminium alloy work pieces.
