Abstract
PURPOSE: To prevent the occurrence of irregular white colors produced after a treating object is pulled up, and enable the automation of rising by electrolytically polishing said object at prescribed temps. then maintaining electrode potential until the bath temp. near the object evolving heat attains lower than prescribed temps. and the object is pulled up.
CONSTITUTION: A treating object of Al or Al alloy is immersed in an electrolytic polishing bath (85% phosphoric acid soln.) of 50W65°C bath temps. Next, while DC electricity is conducted to this object, the object is osicllated, and is thereby electrolytically polished. Next, the electrolyzing voltage is dropped without immediately pulling up the object after the electrolysis, and the bath is maintained at the potential of the extent of preventing chemical attack. When the bath temp. attains ≤70°C near the object evolving heat, the object is pulled up. By this method, the luster of polishing is maintained without producing white turbidity on the surface of the object in a short time after it is pulled up and the object can be rinsed with an automatic rinsing machine.
