Zur Kenntnis der elektrolytischen Abscheidung von Metallpulvern: Die Bedeutung der Diffusionsvorgänge an der Kathode

Abstract: Bekanntlich erhalt man bei der elektrolytischen Abscheidung von Metallen wie Cu, Ni usw. bei massigen Stromdichten kompakte Uberziige mit normalem metallischem Glanz, wahrend bei Steigerung der Stromdichte von einer gewissen Grenze an ein unzusammenhiingender mehr oder weniger dunkel gefarbter Niederschlag entsteht. Dieses Problem der elektrolytischen Abscheidung von Metallpulvern wird in neuerer Zeit ziemlich stark bearbeitet l), was wohl in erster Linie auf die wachsende Bedeutung der Pulvermetallurgie2) zun… Show more

“…Thus the empirical observation was made by several authors that i d 7 = constant, where i is the current density and T the time of deposition at which the first appreciable dimming of reflection was observed from an initially polished cathode. For example, Ibl and Trumpler (1952) found id,= 88.1 and 235 mA sl/z cm-2 for copper deposited from 0.1 and 0.3M CuSO4, respectively, on polished copper. In terms of deposit thickness H this becomes Hdi= constant.…”

“…This stage of appreciable dimming of reflection corresponds to a surface roughness having projections of the order of the wavelength of light in diameter and height. Ibl and Trumpler (1952) and Ibl(l954) considered theoretically the origin of this expression, related to the fact that the rate of supply of cations to the growing cathodic deposit is limited by diffusion of the ions from the solution further away.…”
