ABSTRACT:
A vacuum furnace for the ionic surface treatment of workpieces in which the workpiece is connected as one of a pair of electrodes of opposite polarity, and in which a third electrode is located adjacent the workpiece and is connected to it at the same polarity and potential so as to be subject to the same current density as the workpiece, the current through the third electrode being used to indicate said workpiece current density and to control it.
