Abstract

See full text

An in-situ method for changing surface features of a metal workpiece. An electrically conductive workpiece is immersed in a bath containing an electrolyte solution devoid of ions corresponding to the workpiece. A counter electrode is immersed in the bath. An electric power supply is connected to the workpiece and the counter electrode. An electric current is passed in a first direction between the workpiece and the counter electrode, while the workpiece serves as an anode. The electric current polarity is reversed to pass the electric current in a second direction between the metallic workpiece and the electrode, while the workpiece serves as a cathode. The electric current polarity in the first direction drives ions from the workpiece into the electrolyte solution, and the electric current polarity in the second direction plates the ions onto the workpiece in the same bath.
