Abstract
A method for anodizing a part made of aluminum or an aluminum alloy by immersing the part in an aqueous bath essentially comprising sulfuric acid at a concentration of 150 to 250 g/L and at a temperature of 5 to 25° C. A DC voltage according to a voltage profile comprising a voltage increased at a rate of 1 to 32 V/min is applied to the part. The voltage is maintained at a plateau voltage value of 12 to 20 V for a duration sufficient for obtaining, at the surface of the part, an anode layer having a thickness of 3 to 7 μm and/or a layer weight of 20 to 150 mg/dm.
