Abstract

Improved apparatus and method for the electrodeposition of aluminum and its alloys using aprotic, oxygen and water-free organoaluminum electrolytes, utilizing a rotatable, triple-chambered treatment barrel which provides a greater ratio of anode to cathode surface area and also decreased spacing between anode and cathode, and further applying centrifugal force to the treatment barrel to assist the draining and removal of electroplating and rinse solvents.
