Objects of investigation: processes of chemical reduction of metals and chemical besieging of inorganic tapes from water solutions on dielectrics and metals in the mode of convectional diffusion and forced mass transfer. Purpose: to explore influencing of hydrodynamic terms on verge of distributing of phases on kinetics and mechanism of processes of chemical reduction of metals from water solutions. Methods: gravimetry, chronopotentiometry, spectrophotometry, X-ray diffraktometry, resistometry. Scientific novelty: the effect of hydrodynamic limitation of speed (GDLS) for the reactions of chemical reduction of tin, copper on dielectrics is first set, and also direct and reverse contact exchange of lead on an aluminium and copper accordingly; the effect of the additional activating of catalytic surface of dielectrics before chemical metallization is set; shown opposite influence of additions of surfactants on kinetics of processes of chemical reduction of metals and in the systems of contact exchange; the physical and chemical model of processes of chemical reduction is formulated on dielectrics and metals and the mathematical terms of its capacity are certain. Practical value: it is possible to draw on got new results of researches at development of new technologies of chemical metallization with the purpose of intensification of these processes and upgrading the formed metallic precipitations.
