ABSTRACT:
Provided is a device useful for the uniform electrolysis of a metal sheet workpiece. It is especially useful for the laboratory scale testing of various methods of electrolytically etching aluminum. The device has a generally rectangular frame having non-electrically conducting walls capable of containing an electrolyte; at least one electrode; electrically conducting clamping means to rigidly hold a metal workpiece within the frame at a fixed distance from the electrode; means for circulating the electrolyte about the workpiece; and means for applying a current between the workpiece and electrode.
