A Radioisotopic Study of Leveling in Bright Nickel Electroplating Baths

Abstract

A radioisotope-containing addition agent has been synthesized and used as a component in a bright and leveling nickel bath. Investigation by autoradiography and counting techniques shows that this agent is deposited preferentially at the high points of an irregular surface, thereby substantiating a part of leveling theory. The radioactive addition agent also is used in an attempt to understand better the mechanism of formation of laminations in this type of nickel deposit. © 1959, The Electrochemical Society, Inc.
