, (0932)35-18-51 Received August 19, 2004 Abstract — The effect of electric conditions on the cathodic deposition of silver from pyrophosphase-ammonium electrolytes is studied. A pulse-current mode is shown to enhance cathodic polarization. This effect increases with an increase in the relative pulse duration. The advantages of nonsteady-state electrolysis for the improvement of the uniformity and structure of silver deposits formed on the inner surface of a cylindrical cathode are demonstrated.
