ABSTRACT:
Improved apparatus and method for the electrodeposition of aluminum and its alloys using aprotic, oxygen and water-free organoaluminum electrolytes, involving a method for removing water from pretreated workpieces and locating them in a plating barrel without exposure of workpieces to air, and further 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.
