SIMULATION OF LOOSE DEPOSIT ELECTROCRYSTALLIZATION FROM AN AQUEOUS-SOLUTION - LOCALIZATION OF HYDROGEN-ION REDUCTION AND METHODS FOR ITS REMOVAL

The mechanism of hydrogen evacuation from the cathodic surface in the reduction process during crystallization of a copper dendrite deposit is studied. The processes of hydrogen formation and evacuation are fou nd to be governed by regularities of gas evolution in electrolysis wit h a porous electrode, whereas the reaction of hydrogen ion reduction o ccurs practically over the entire extended deposit surface. The relati on between the area, which is occupied by gas channels at the disperse d deposit surface, and the cathode potential is obtained.
