“…8), the hydrogen libera tion intensity considerably lowers as the dendritic dep osition grows. According to [6], a decrease in velocity leads to an increase in the thickness of the diffu sion layer δ ef : (8) where ν is the kinematic viscosity of the solution and D is the diffusivity.…”

“…There is a crystallization model of the dendritic deposition which involves parallel cathodic hydrogen liberation; however, it does not take into account the enhancement of the convective diffusion of metal ions to the cathode caused by this reaction. The connection between the hydrogen liberation rate and the effective thickness of the diffusion layer is taken into account in [6], but the empiric relationship between them should be refined.…”

Abstract-This study is associated with the solution to the blending problem of the charge for the output of ready articles. The main requirements are claimed to the specific surface and the packed density of the pow ders of basic brands PML0, PMS 1, and GG. The dynamics of the development of the dendrite depositions for powders of mentioned brands with the simultaneous registration of the cathodic overvoltage is investigated under industrial experimental conditions. The procedure is developed and the results of the continuous mon itoring of the deposition growth with the direct immersion of a video camera into the electrolyte are pre sented. The reproducibility of the results is evaluated statistically. Based on the galvanostatic crystallization model of the dendrite deposition on the rod electrode, the dynamics of varying the density (N) and radius (r t ) of growing tips on the growth front is calculated. It is established by variance analysis that structural param eters N and r t are individual for depositions of every brand, so that the preparation conditions of the deposi tion during the electrolysis should be strictly fulfilled as the charge forms.
