Abstract
PURPOSE: To enable to carry out a high quality coloring treatment, by changing by slowly boosting alternating current voltage applied between both electrodes together with optional boosting time from the early stage applied voltage to the last applied voltage.
CONSTITUTION: Data obtained a good coloring result, is previously memorized in the magnetic card, on occasion of carrying out alternating current electrolytic coloring of aluminum anodic oxidation coating. The above card is inserted in the read and record machine 6 and alternating current voltage applied between electrodes of electrolytic bath 1 through the microcomputer 5, the control board 3 and the power source 2, is boosted and changed together with optional boosting time at a speed of 0.01W10V/sec automatically from the early stage applied voltage to the last applied voltage of 5W30V in a fixed way. Superior coloring is obtained by carrying out the above coloring treatment and also, treating time is shortened. Further, the alternating current voltage between the electrodes of the bath 1, is able to change so as to be carried out a fixed boosting. On this occasion, current variation is memorized in the card of the machine 6.
