The kinetics of cementation of silver chloro-complexes from sodium chloride solutions onto copper and zinc was studied using rotating disc electrode system. The activation energies were found to be 10.8 and 30.5 k7/mole, in a 3M NaCl solution on copper and zinc discs, respectively. Higher dissolution factors were obtained on zinc disc, due to hydrogen evolution, whereas, copper dissolved close to the predicted values. Scanning electron microscope studies were conducted both on copper and zinc- cdiscs-to evaluate the deposit morphology and its effect on reaction kinetics. Two stage deposit growth was observed both on copper and zinc discs. Smooth, coherent initial deposit followed by tree-like secondary dendrites formed on copper, whereas, scattered bulbous initial deposit followed by porous dendrites was typical on zinc disc.
