Abstract
A plate-, foil- or web-shaped workpiece of aluminum or an alloy thereof is subjected, in an electrolyte bath, to an alternating current at a frequency of 0.1 to 25 Hz. During the AC treatment, an anodic potential is imposed on the workpiece, in the range of 0 to 5 Volts. The total charge input is 10 to 60 kC/m.sup.2. Prior to the electrochemical graining, the workpiece is mechanically grained. After the graining steps, an etching treatment as well as an anodical oxidation and, thereafter, a hydrophilization are performed.
