Research in the electrodeposition of metals by a cyclic variation or interruption of the applied current offers exciting alternatives for the electroplater and electroplating engineer. Optimized pulse plating conditions produce many desirable deposit characteristics, which are enumerated in the text. The text deals with the theoretical aspects of pulse plating, the results of numerous research studies related to metallic deposition with interrupted current techniques, practical applications for pulse plating and a review of pulse plating equipment that has become commercially available for the electroplater. It is intended to serve as a valuable reference to engineers who select finish specifications for metals and electroplaters engaged in the field of electrolytic metals deposition.
