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 powders 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 monitoring of the deposition growth with the direct immersion of a video camera into the electrolyte are presented. 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 parameters N and r t are individual for depositions of every brand, so that the preparation conditions of the deposition during the electrolysis should be strictly fulfilled as the charge forms. © 2013 Allerton Press, Inc.
