METHOD FOR ANODIZING ALUMINUM-COPPER ALLOY

摘要

An anodization method includes steps of providing an object formed of an aluminum-copper alloy, providing an anodizing bath comprising a basic silicate solution, providing an AC power supply including a first electrode and a second electrode, placing the first electrode in contact with the anodizing bath, connecting the second electrode to the object, placing the object in the anodizing bath, applying a voltage to the first and second electrodes to maintain a current density of about 10 mA/ cm² or less to form an anodized coating on the object, removing the object from the bath, and sealing the anodized coating on the object.
