ABSTRACT:
In anodizing aluminum the primary power source is three phase which is converted into six phase and each current in each of such six phases flowing through an anodizing bath is controlled as to intensity and form with a large positive pulse followed by a smaller negative pulse and with the rate of such pulses being adjustable within the range of one to twenty per second for control of shade of the anodized aluminum.
