Problems encountered in pulsed electrodeposition were reviewed. It has been said that pulsed current can cause a profound change in the morphorogy of electrodeposits making them harder, more uniform and more compact, with better adherence to the substrate. The effect of the pulsed current, however, is not necessarily the same for all metals because the rate determining step of the deposition reaction affected by the pulsed current in each case is the rate-determining step. The use of pulsed current improves microcurrent distribution provided concentration polarization develops at the crests and recesses in the electrode surfaces.
